What is Detect Unicode Char?
The Unicode Character Detector is a diagnostic tool that reveals the underlying structure of your text. Every character you see on a screen is backed by a unique Unicode code point. Sometimes, text contains invisible characters (like Zero Width Spaces), confusing look-alike characters (homoglyphs), or complex emoji sequences that can cause issues in programming, data processing, or display. This tool breaks down your text character by character, showing you the Unicode Code Point (e.g., U+0041), the official Name (e.g., LATIN CAPITAL LETTER A), and the visual representation. It's essential for debugging encoding issues and sanitizing inputs.

Frequently Asked Questions
What is a Zero Width Space?
It's a character (U+200B) that has no width and is invisible, but acts as a boundary. It often causes 'mysterious' bugs in code.
Why do some emojis have multiple codes?
Many emojis are sequences of multiple characters joined together (e.g., a family emoji might be Man + Woman + Boy joined by Zero Width Joiners).
What is a Code Point?
A code point is a unique number assigned to each character in the Unicode standard (e.g., U+0041 for 'A').
Why do I see square boxes?
If you see a square box (tofu), it means your device doesn't have a font that supports that specific character.
Does it detect homoglyphs?
Yes, by showing the code point and name, you can easily distinguish between look-alike characters (like Latin 'a' vs Cyrillic 'а').
Can I copy the code points?
Yes, the tool provides a table where you can copy the code point, name, or the character itself.
Is there a limit on text length?
The tool can handle large blocks of text, but processing extremely long strings might take a moment.
