Unicode, UTF-8, and Why Encoding Matters for Developers

Unicode assigns code points to characters. UTF-8 encodes those code points as bytes — variable width, backward compatible with ASCII, dominant on the web.

Failure modes

• Reading UTF-8 bytes as Latin-1 → mojibake.
• Splitting strings on byte indexes mid-sequence → corrupted emoji.

Encode binary safely for text channels with Base64 after UTF-8 serialization.
