Hmm, I am actually not sure what I meant  :)

The mark actually is not necessary for noting down some byte order or
something. We could also use an arbitrary character that is unlikely to
start a word and does not disturb the file loading in photoshop too
much. We could even try if one of the ASCII control characters is
invisible to photoshop users.

I originally did not plan to use some kind of mark for "our" utf-8
encoded strings: Just try to decode it as UTF-8 and if it works it
probably was an UTF-8 encoded name. If it doesn't work we fall back to
the adobe-iso-whatever encoding. But Franz thought it would be easier to
just have this kind of marker would be useful.
