On my SunOS 4.1.3's /usr/include/ctype.h:

#define isprint(c)      ((_ctype_+1)[c]&(_P|_U|_L|_N|_B))

Where "_ctype_[]" array is the contents of the locale/LC_CTYPE file
that's current, and the "_P", etc. flags are bit codes for the
different types a character that the ctype routines need to know
about.

I have "LC_CTYPE=iso_8859_1" in my environment, and it works as advertised.


I think the problem needs to be defined better.  Are your umlauts
dissappearing entirely (a zsh problem) or are they being meta-ized
(\M-? - an OS problem), or perhaps they are coming through, but your
terminal emulator can't display them correctly (a S.O.L. problem)?

A good operating system would have locale settings such as "C",
"iso_*", and any non-standard charset it used, such as, "next", "mac",
"ebcidic" or whatever.  Then you would set your LC_CTYPE variable
according to what character set you are using today.

Now if NextStep can only do "C" (isprint()) or "next" (NXisprint),
then that's fine if that's all your using.  But if your terminal
emulator can only do iso_8859_1, like xterm, then your screwed when
it comes to displaying any non-ascii nextstep characters.  (Unless
there's a specially hacked Next xterm that understands its charset?)

I would guess this isn't the problem, or else you wouldn't be
complaining just about zsh, but about everything.

If you think it's a zsh problem, can zsh glob filenames with
these characters properly: "echo *"?

Can you type these characters, is the problem only in completion?

Do other programs, such as "ls" or "less" have problems?

I hope this helps the discussion.
