Frequently Asked Questions

What is Unicode escape encoding?
Unicode escape sequences represent characters using their hexadecimal code point. The format \uXXXX represents a BMP character (4 hex digits), while \u{XXXXX} represents any Unicode character (1-6 hex digits).
What does the character details panel show?
For each character, it shows: Unicode code point (U+XXXX), UTF-8 byte sequence, HTML entity (decimal and hexadecimal), character name, block/script, and category (Letter, Number, Punctuation, etc.).
How do I convert escape sequences back to characters?
Paste the escape sequences (like \u4e2d\u6587 or \u{1F600}) and select Decode. The tool converts them back to readable characters.
What is the difference between \uXXXX and \u{XXXXX}?
\uXXXX is the older format limited to 4 hex digits (BMP characters, U+0000 to U+FFFF). \u{XXXXX} is the modern ES6 format that supports all Unicode characters including emoji (up to U+10FFFF).
Is my data sent to a server?
No. All conversion and character analysis happens locally in the browser using JavaScript's String and Unicode APIs.
