What makes you think there's a "right answer"? Why can't two or more
different groups disagree? We already have disagreement, as indicated
by the various R5RS implementations, as to whether case-folding in ASCII
identifiers is the right thing or not.
(I say "two or more" because there are two kinds of diacritics in
Vietnamese, those that mark tone and those that distinguish separate
vowels. The former are thought of as diacritics, the latter as part
of the vowel letter, just as the dots in ä (a-diaeresis) and ö
(o-diaeresis) are in Swedish -- but not German.)
For that matter, I note that while the non-normative section 2.1 of
The precise rules for forming identifiers vary among
implementations of Scheme, but in all implementations a sequence
of letters, digits, and "extended alphabetic characters"
that begins with a character that cannot begin a number is an
identifier. In addition, +, -, and ... are identifiers.
the formal syntax in 7.1 prescribes a fixed syntax for identifiers that
does not permit any such "extended alphabetic characters."
