UTF-8 ensures that no non-ASCII character can be confused for an ASCII
character.  Everthing not in 0 <= code_point < 128 has the most
significant bit set.

On that front, I hope to see UF-8 specified as the encoding for any
text in exr files, and agree that 255 *octets* is a reasonable maximum
length for channel names, but it may be a good idea to specify that
the 255 octets should hold an integer number of UTF-8-encoded characters.
Ie, truncate at a whole character, not in the middle of a multi-octet one.
