How text is converted to hex
Each character is first encoded as UTF-8 bytes — one byte for ASCII, two to four bytes for non-ASCII characters. Each byte is then written as two hexadecimal digits (00–FF). So the letter "A" (byte 0x41) becomes 41, and "👋" (bytes F0 9F 91 8B) becomes f09f918b.
When to use

- Debugging non-ASCII data flowing through APIs.
- Feeding binary values into low-level protocols.
