No, that's deliberate: any byte >= octal 200 is allowed as part of an
unquoted identifier.  Non-English-speaking users would get quite upset
with us if they had to quote, say, e-acute to use it in an identifier.

Ideally I suppose we'd restrict it to just characters that actually have
some letter nature to them, but the trouble with that is it'd make the
backend lexical rules encoding-dependent, which is bad news for a number
of reasons.  So we allow 200-377 in all cases.
