Byte representation is separated from Unicode text
The review reports exact UTF-8 bytes, strict decode status, BOM presence and round-trip behavior so hex/decimal/binary notation is not confused with Unicode code-point notation.
Parse binary octets locally and reject malformed UTF-8 sequences instead of silently replacing invalid bytes.
These tools operate on bytes and Unicode text locally. “Text to hex/binary/decimal” means the UTF-8 encoding of the text, not the numeric Unicode code point unless a tool explicitly says code point.
