How to use Convert UTF8 to Unicode
- 1. Paste the UTF-8 bytes. Paste the UTF-8 bytes you want decoded back to text, written as space-separated hexadecimal values such as 41 42.
- 2. See multi-byte sequences grouped. The tool reads the bytes in order, groups multi-byte sequences according to the UTF-8 pattern, and renders the resulting code points as ordinary readable characters.
- 3. Copy the decoded text. Copy the decoded text and use it to confirm what a run of UTF-8 bytes actually spells out, whether it came from a hex dump, a network capture, or a file inspection.
When to use Convert UTF8 to Unicode
Convert UTF8 to Unicode turns a sequence of raw UTF-8 bytes back into readable text, correctly grouping multi-byte characters instead of treating every byte as its own letter. It is for whenever you are staring at bytes and need to know what string they decode to.
- Reading bytes from a packet capture. A tool like Wireshark shows a payload as raw hex bytes, and decoding a suspected UTF-8 sequence here reveals the actual text message being transmitted.
- Debugging a file with the wrong extension or corrupted header. A file's contents look like garbage in a text editor, and pasting its raw bytes here checks whether it is valid UTF-8 that a broken tool is misreading.
- Verifying a hardcoded byte array in code. A codebase has a hardcoded array of byte values meant to represent a string constant, and decoding it here confirms it still matches the intended text after a refactor.
- Investigating mojibake in an exported file. An exported CSV or log shows strange characters instead of expected text, and decoding the raw bytes here checks whether the file is valid UTF-8 or a different charset entirely.
