Frequently Asked Questions
Any character with a code point above 127 (i.e. non-ASCII) is converted to a 4-digit hex \uXXXX sequence; standard ASCII letters, numbers, and punctuation are left unchanged.
Not fully — since it operates on JavaScript's UTF-16 code units rather than full code points, characters represented as surrogate pairs (many emoji) will be escaped as two separate \uXXXX sequences rather than one combined code point escape.
Yes — the Unicode Unescaper tool converts \uXXXX sequences back to their original characters.
No — conversion happens entirely in your browser.
