My only information about the UTC's decisions is what passes on this mailing
list, so I trust you.
But I know that character names are not going to change, and I think that
the same is true for normative character properties (correct?), so how can
the current semantic be so radically changed?

OK. Thank you for reminding this, although I didn't say that it has "no"
However, a ZWNBSP at the beginning or end of a file (or even at the
beginning or end of a paragraph) has no such implications with hyphenation
and -- more important -- it has no practical effect.
So what I meant still holds true, I think: applications that implement
heuristics for detecting UTF-8 will benefit of a ZWNBSP at the beginning of
a file (the detection will be much faster and safer), but they do not
On the other hand, applications that don't implement such a thing can quite
safely treat any ZWNBSP as a normal character.
