Whether len bytes starting at off are well-formed UTF-8.

Whether a byte may start a code point (i.e. is not a continuation byte). Field slices of a valid buffer are themselves valid iff every field starts on a boundary.

Decode a byte slice exactly like decodeUtf8Lenient: greedy decode at each position; any byte that cannot begin a complete, valid sequence within the slice becomes one U+FFFD and decoding resumes at the next byte.

Slice forced Text values off a shared array; row i spans bytes [offs!i, offs!(i+1)). Fast path validates the whole span once when every field starts on a code-point boundary; else per-field validation with lenient decode.
