What are Invisible Characters?

Invisible characters look like empty spaces, but they’re actually special Unicode symbols. You can’t see them, but computers and apps still recognize them as real text. They’re often used to trick platforms into accepting “blank” names, send empty messages, or add hidden spacing. It’s like typing something that’s there but completely invisible to the human eye.

Suggested Tool - Invisible Text Detector & Remover Tool

If you’re trying to remove hidden characters from your text (not just copy them), we also offer a Free Invisible Text Detector & Remover Tool.

 It helps you:

  • Detect invisible Unicode characters in any text

  • Remove problematic or unnecessary ones

  • Fix formatting issues caused by copy-pasted LLM content (like Em Dashes or ZWSPs)

Perfect for editors, coders, and anyone debugging odd text formatting.

How are Invisible Characters Used?

These characters can be used to create unique usernames, send “empty” messages on messaging platforms or for testing software. 

  • Usernames & Display Names
    • People use invisible characters to create completely blank profile names or to bypass "name already taken" restrictions. This is popular on platforms like Instagram, WhatsApp, Discord, and Roblox.
  • Empty Messages / Chat Pranks
    • Users send totally blank chat bubbles in iMessage, Android SMS, WhatsApp, and Discord for fun or to keep streaks going.
  • Creative Spacing & Formatting
    • Invisible characters are often used to insert precise spacing in bios, stories, or captions, especially on Instagram and TikTok.
  • Bypassing Filters or Minimum Length Rules
    • These characters can bypass input restrictions in forms that require text or block certain characters.
  • QA Testing & Bug Discovery
    • Software testers use invisible characters to uncover encoding or trimming issues in applications. They help reveal how an app handles non-printing Unicode.

TikTok

TikTok users chased the viral “blank profile” trend during 2021–22; the Object Replacement Character seems to be the best option for TikTok.

  • Use-Case 1 - Invisible Display Name

    • Recommended code: U+FFFC (Object Replacement Character)
    • Reference: Reddit success thread Reddit
    • Notes: Works in the “Name” field; often blocked in “Username.”

  • Use-Case 2 - Blank Comment / Caption Spacer

    • Recommended code: U+200B (Zero-Width Space)
      Reference: Generic ZWSP resource Unicode Explorer
    • Notes: Paste once for an empty comment; pad hashtags invisibly by repeating twice.

Instagram

Creators use invisible text for empty bios, secret line-breaks, and the legendary “nameless” Among Us profile screenshot that went viral on IG Stories in 2020.

  • Use-Case 1 – Blank Display Name / Bio Line

    • Code: U+3164 (Hangul Filler “ㅤ”)
    • Comments: Accepted in the Name & Bio fields; if trimmed, add a second copy.

  • Use-Case 2 – Aesthetic Story Spacing

    • Code: U+200A (Hair Space)
    • Comments: Insert multiple Hair Spaces to create precise kerning or blank slides.

WhatsApp

Overview - Blank messages are a classic prank; thousands of YouTube shorts show the “send empty chat bubble” trick.

  • Use-Case 1 – Empty Chat Bubble

    • Code: U+3164 (Hangul Filler “ㅤ”)
    • Comments: Works on Android & iOS; add 3× for older devices if single char fails.

  • Use-Case 2 – Invisible Profile Name

    • Code: U+3164 (Hangul Filler “ㅤ”)
    • Comments: Paste once in Name → Save. Contacts will see a blank sender.

Discord

Overview – Gamers hide from @mentions with zero-width tricks; a famous 2019 screenshot showed a totally un-clickable blank DM name (see photo below).

  • Use-Case 1 – Invisible Server Nickname (not always working)
    • Code: U+200B (Zero-Width Space)
    • Reference: Reddit explainer Reddit
    • Comments: Set as Nickname; appears blank in member list.

  • Use-Case 2 – Blank Message / Spoiler Gap
    • Code: U+200D (Zero-Width Joiner)
    • Comments: Paste once; Discord sends an empty line—great for spoiler spacing.
https://www.reddit.com/r/discordapp/comments/dgbnhg/how_is_this_even_possible_unselectable/

Twitter / X

Overview – Users periodically share “How to get a blank display name in 30 sec” threads; the Arabic combining mark is the current winner after earlier fillers were patched. Copy Paste Dump

  • Use-Case 1 – Invisible Display Name

    • Code: U+064B (Arabic Fathatan)
    • Comments: Copy once; hit Save. If blocked, try double-pasting.

  • Use-Case 2 – Blank Tweet

    • Code: U+FE0F (Variation Selector-16) + normal space
    • Comments: Paste VS16, add one space, post—tweet looks empty in feeds.

Roblox (and Other Games: Fortnite, Free Fire, Steam)

Overview – “Ghost player” display names exploded on YouTube tutorials; dev-forum threads track every new Unicode patch.

  • Use-Case 1 – Blank Display Name

    • Code: U+3164 (Hangul Filler) or U+FFA0 (Half-width Filler)
    • Comments: Roblox may flag U+3164—try the half-width variant as backup.

    • Code: U+2800 repeat × 20 for title padding
    • Comments: Creates a “secret” game only accessible via direct link.

Texting (iPhone and Android)

Overview - Native texting apps (Apple iMessage on iPhone, Google Messages / Samsung Messages on Android) block plain spaces, so you cannot press “Send” on an empty bubble. So you need to paste a non-printing Unicode character. TikTok compilations of “send a blank text to your crush” still circulate, and Apple’s own Messages app doesn’t flag the trick.

  • Use-Case - Send a Blank Text

    • Code: U+2800 (Braille Pattern Blank)
    • Comments: Paste once → Send. Shows a completely blank bubble on both platforms. If iOS17 auto-collapses it, paste twice.

Alternatively, you can use the “Invisible Ink” Feature on iPhones

Founder / CEO of Originality.ai I have been involved in the SEO and Content Marketing world for over a decade. My career started with a portfolio of content sites, recently I sold 2 content marketing agencies and I am the Co-Founder of MotionInvest.com, the leading place to buy and sell content websites. Through these experiences I understand what web publishers need when it comes to verifying content is original. I am not For or Against AI content, I think it has a place in everyones content strategy. However, I believe you as the publisher should be the one making the decision on when to use AI content. Our Originality checking tool has been built with serious web publishers in mind!

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

In The Press

Originality.ai has been featured for its accurate ability to detect GPT-3, Chat GPT and GPT-4 generated content. See some of the coverage below…

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

What Files Can You Inspect with This Text Compare Tool?

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

Will My Data Be Shared?

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
