Frequently Asked Questions
How is A encoded?
01000001 — 8 bits: 64+1. Each character maps through its code point; the tool shows byte boundaries explicitly.
Unicode beyond ASCII?
Yes — UTF-8 multi-byte sequences encode fully (é becomes two bytes). Byte counts exceed character counts for non-ASCII text.
Learning use?
CS classes demonstrate encoding live: type names, watch bits. Separators make nibble structure visible.
Do encoded strings upload?
No — encoding runs locally in your browser. Text never leaves your device.
