Questions

How do I convert Unicode character codes back to text?

Enter separated character-code values and select their Base and Delimiter. The default base is hexadecimal. This operation reconstructs characters and returns their encoded byte representation, which can appear as a downloadable binary result.

How is a character code different from a UTF-8 byte?

A Unicode character code identifies a character value. UTF-8 can encode that value with several bytes. Use Hex Decoder for hexadecimal UTF-8 byte sequences, and Charcode Decoder for character-code values.

Why should I keep separators between character codes?

Separators make variable-length values unambiguous. Match the Delimiter setting to the input instead of concatenating codes. A long uninterrupted string can trigger a different grouping path and produce characters you did not intend.
