--- Comment #1 from nick black <nickblack at linux dot com> ---
If I add a call to setlocale(LC_ALL, "") with a proper LANG environment
variable and installed locale data, I get the expected result (which is 1, and
agrees with modern utf8proc):

[schwarzgerat](0) $ cat test.c
#include <stdio.h>
#include <locale.h>
#include <wchar.h>
#include <utf8proc.h>
int main() {
  setlocale(LC_ALL, "");
  wint_t c = 0x2630;
  printf("wcwidth returns %d\n", wcwidth(c));
  printf("utf8proc_charwidth returns %d\n", utf8proc_charwidth(c));
  return 0;
}
[schwarzgerat](0) $ gcc -D_XOPEN_SOURCE test.c -lutf8proc
[schwarzgerat](0) $ ./a.out
wcwidth returns 1
utf8proc_charwidth returns 1
[schwarzgerat](0) $

I believe this bug can be closed. The test program provided requires a
setlocale() call to produce the expected result.

Without setlocale, you are using the C locale, with the ASCII codeset.
