I noticed this failure in various configure scripts (findutils, coreutils, ...):
checking whether wcwidth works reasonably in UTF-8 locales... no I've reduced it to a STC: #include <locale.h> #include <wchar.h> int main () { int i = 0; if (setlocale (LC_ALL, "fr_FR.UTF-8") != NULL) { if (wcwidth (0x0301) > 0) i |= 1; if (wcwidth (0x200B) > 0) i |= 2; } return i; } The return value should be 0 but is coming back as 3; 0x0301 is a combining mark which should occupy no space on its own, and 0x200b is a 0-width space, according to Unicode 5.1 (and earlier, to some extent). And that probably means that other places within wcwidth() are broken. -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
