FAQ
How does text become binary?
Text is encoded as UTF-8 bytes, and each byte is shown as exactly 8 binary digits.
What are the quick presets?
A (01000001), emoji 👋, and Hello — common classroom/demo inputs.
How strict is binary decoding?
Grouped input requires exactly 8 bits per group. Continuous input must contain only bits and have a length divisible by 8. Invalid UTF-8 is rejected.
Does it support emoji and accents?
Yes — UTF-8 multi-byte text is handled correctly, with separate grapheme, code point, UTF-16 and byte counts.
