it's making no assumptions about encoding.
Actually it is! It assumes that the first character is the first
"character". You'll want to stick in a call to
-rangeOfComposedCharacterSequenceAtIndex: if you want to be 100%
universal.
However I would not hesitate to assume ASCII. The language only allows
ASCII in identifiers, so you can't define, declare, or call a
non-ASCII method directly in code. You could do so by building one at
runtime, but if you're doing such a crazy thing then you deserve
whatever poor behavior you get!
In fact the language allows some strange things.
C99 allows usage of some UCN in identifier (see annex D of C99
reference fo know the full list):
And so, this is valid Obj-C99 (obj-c code compiled using -std=c99) code.
