Here's one I wrote a little while ago, which will show you the ctype map
for the entire character set, as it appears for your locale. If it shows
all of the upper-half of the character set as control characters (c),
rather than some alphabetic characters (A with u or l), then you have a
problem with your locale. You can try various locales using a command
line argument. If you find one that works, try changing the LC_CTYPE
to LC_ALL in the setlocale() call, to make sure it still works that way.
If it works both ways, that locale should work with htdig.
If you can't find a locale that works, and you can't get anything
to work even if the locales are fully installed, then it may be that
locale support in your C library is broken. I know from experience
that locale support in libc-5.3.12 on my Red Hat 4.2 Linux system does
not work, and I wouldn't expect much from any libc5 based Linux system.
(I have yet to see a counter-example of this posted on this list.)
On the other hand, glibc 2.0 & 2.1 based Linux systems (e.g. Red Hat
5.x & 6.x) seem to have proper locale support.
