Only for ASCII text. Multi-byte UTF-8 characters like emoji or accents take up more than one hex pair.
How text becomes hexadecimal
Each character is first turned into UTF-8 bytes, then each byte is written as two hexadecimal digits (00 to ff). The letter "A" is byte 65, written as 41 in hex.
This representation is common in programming, debugging network traffic, and working with binary file formats where every byte needs to be visible and editable as text.
