Hi, I'm having a bit of trouble to make regular expressions in grep using isalpha() and related functions work. (Seen man 1 grep, man 7 regex and man 3 isalpha). The LC_CTYPE section of /usr/share/i18n/locales/en_US and mk_MK copy /usr/share/i18n/locales/i18n, in which <U2026> (HORIZONTAL ELLIPSIS) is defined as a punctuation character. Using a gnome-terminal for which I can set the character encoding, so the below examples are converted back to UTF-8 in this mail (I switch encoding after each "export LANG", which doesn't matter for the matching by the way). "\xe2\x80\xa6" is the UTF-8 equivalent of the horizontal ellipsis, "\x85" is the CP1250/1/2 equivalent. $ export LANG=en_US.UTF-8 $ echo -e "\xe2\x80\xa6" … $ echo -e "\xe2\x80\xa6" | grep "[[:punct:]]" … $ export LANG=en_US.CP1252 $ echo -e "\x85" … $ echo -e "\x85" | grep "[[:punct:]]" $ export LANG=en_US.CP1251 $ echo -e "\x85" … $ echo -e "\x85" | grep "[[:punct:]]" $ export LANG=en_US.CP1250 $ echo -e "\x85" … $ echo -e "\x85" | grep "[[:punct:]]" $ export LANG=mk_MK.CP1251 $ echo -e "\x85" … $ echo -e "\x85" | grep "[[:punct:]]" $ Note that CP1251 is explicitly mentioned in mk_MK. Now why doesn't the horizontal ellipsis get matched as a punctuation char? Is this a bug? Is so, where? If not, how do I accomplish the match?
