decode_text

Decode UTF-8 bytes without trimming or newline conversion. Malformed input raises InvalidUTF8Error by default. invalid=:replace uses one U+FFFD per maximal subpart; valid adjacent characters remain intact. The returned text does not alias caller-owned bytes.

decode_text(bytes::AbstractVector{UInt8}; invalid=:error)

The replacement contract follows Unicode 17, section 3.9.6.
