—About Unicode Encoder
The Unicode Encoder rewrites text as \uXXXX escape sequences, optionally limiting the conversion to non-ASCII characters. It is aimed at developers embedding text in source code, JSON, or config where non-ASCII characters need escaping.
Some toolchains mishandle raw non-ASCII bytes. Converting to \u escapes keeps strings portable across encodings, and doing it locally means your text is never exposed.
Step by step
- Type or paste the text you want to escape.
- Choose whether to escape every character or only non-ASCII ones.
- The escaped output is produced as you type.
- Copy the result into your source or config.
What it offers
- uXXXX escape conversion
- Optional non-ASCII-only mode
- Live output
- Encoded on your device — Unicode Encoder
Tips for best results
- Escape only non-ASCII characters when you still want the result to be mostly readable.
- Confirm your target language uses \uXXXX syntax — some use \x or &#; instead.
- Pair with the decoder to verify the escaped string round-trips back to the original.
