I was about 50/50 whether the double negation was too ugly to use. :) I'll leave the function there, but name it maybe_c32isnbspace(). Since I don't want the function to be misunderstood as a wchar_t function. Pushed the attatched two patches. The second fixes a 'make syntax-check' failure. Will close this bug now. Collin P.S. I actually just noticed this unchanged hunk in my diff: $ git ls-files | grep -E '\.[ch]' | xargs grep -F 'isw' src/wc.c: in_word2 = (! iswspace (wide_char) Okay to change this one to the c32 variant?
