How it works
This tool iterates over each character in the input string and escapes any character with a code point above 127 using the \uXXXX format. ASCII characters are left unchanged. Processing runs in your browser.
Common use cases
- Encode Unicode characters as escape sequences for source code embedding
- Convert emoji or non-ASCII characters to Unicode escape codes
- Inspect the Unicode code point of a specific character
