Not sure how to deal with it, but maybe it's just a matter of settling on 
multibyte representation when building the title (as in mode_line_noprop_buf 
and so on)? I presume that the current ambiguity comes from when there were 
good reasons to build these strings in various unibyte encodings, but maybe it 
isn't motivated today?

If it is at all any trouble at all, just leave it as it is. On the other hand, 
perhaps we have found a way to simplify the code by accident.
