Unicode Escape: uXXXX Sequences, Encoded and Decoded

September 20, 2026

By PrimeFreeTools Editorial Team, written from hands-on use of our own tools.

Some parsers, old JavaScript, JSON-ish strings, and logs prefer to see a character as u0041 rather than the letter itself. The escape form travels through systems that mangle non-ASCII without the mangling.

Escape text to uXXXX sequences and unescape them back to readable text. Use it when a string with accented or CJK characters must survive a transport that is not unicode-safe, and decode before you display.

Try it now: open the free tool, runs 100% in your browser.

Bottom line: escape to uXXXX for transports that hate raw unicode.
