Re: deprecated: ISO-Latin1 characters in identifiers, plus Illegal character

Previous OCaml versions tolerated accented characters in identifiers, but
only in Latin1-encoded files (and this had been documented as deprecated
for years). Recent versions will complain about such Latin1 characters in
identifiers, but not allow UTF8 characters (outside the ASCII fragment) to
replace them, given than lexical syntax design tends to be fraught with
difficulties.

I should note that Peter "whitequark" Zotov has proposed a preprocessing
frontend to the OCaml compiler that accepts richer UTF8 identifiers.

My understanding of this work is that it meant more as a technological
display than for end-user consumption right now -- unless you really know
what you're getting into.
