What is Unicode Converter?
Unicode assigns characters to code points such as U+1F30E, while UTF-8 serializes those code points as bytes. They are not the same representation: one supplementary emoji is a single Unicode code point but usually four UTF-8 bytes. This tool converts text to Unicode scalar notation or UTF-8 hex, with strict rejection of surrogate code points and invalid UTF-8 byte sequences.
How to use this tool
- Choose Unicode U+ code points or UTF-8 hex byte notation.
- Enter text to encode, or an encoded sequence to decode.
- Convert and copy or download the result. Check text normalization separately when exact composed/decomposed forms matter.
