/* Whether a string's bytes read as the encoding it is taken to have. A binary
string claims no encoding and is valid whatever its bytes are; any other
string is walked, and one that turns out to hold a byte standing for no
character is not valid. The single-byte flag is not read on the way in, so
the answer does not depend on whether the string has been measured before;
a string found to have one byte per character is marked on the way out. On
non-UTF-8 builds a string is bytes with no encoding to disagree with, and
this is always TRUE. */
