438    Note that \exhh always specifies one byte, even in UTF-8 mode; this makes it
439    possible to construct invalid UTF-8 sequences for testing purposes. On the
440    other hand, \ex{hh} is interpreted as a UTF-8 character in UTF-8 mode,
441    generating more than one byte if the value is greater than 127. When not in
442    UTF-8 mode, it generates one byte for values less than 256, and causes an error
443    for greater values.
