What is hexadecimal encoding?

Hexadecimal (hex) encoding represents each byte of data as two characters from 0-9 and a-f. It is commonly used for colors, memory addresses, and binary data inspection.

How does it handle Unicode characters?

Multi-byte Unicode characters produce multiple hex byte pairs. For example, an emoji might produce 4 byte pairs (8 hex characters).

Is hex encoding the same as hex colors?

Hex colors like #FF0000 use the same base-16 notation, but they specifically represent RGB color values rather than arbitrary text.
