Package: grep Version: 2.14-4 Severity: important Dear Maintainer,
The string '^\s*' is not catched at all when LC_CTYPE is set to any valid UTF-8 locale, but it is when LC_CTYPE is set to anything else (not really; in fact, this also affects 140 other locales + an empty LC_CTYPE). user@sid:~$ locale LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= user@sid:~$ echo 'whatever you want' | grep '^\s*' user@sid:~$ echo 'whatever you want' | LC_CTYPE= grep '^\s*' user@sid:~$ echo 'whatever you want' | LC_CTYPE=C grep '^\s*' whatever you want user@sid:~$ echo 'whatever you want' | LC_CTYPE=POSIX grep '^\s*' whatever you want user@sid:~$ echo 'whatever you want' | LC_CTYPE=FooBar grep '^\s*' whatever you want user@sid:~$ echo 'whatever you want' | LC_CTYPE=not-valid-utf8 grep '^\s*' whatever you want user@sid:~$ echo 'whatever you want' | LC_CTYPE=xx_XX.UTF-8 grep '^\s*' whatever you want user@sid:~$ echo 'whatever you want' | LC_CTYPE=de_DE.UTF-8 grep '^\s*' user@sid:~$ echo 'whatever you want' | LC_CTYPE=es_ES.UTF-8 grep '^\s*' user@sid:~$ echo 'whatever you want' | LC_CTYPE=fr_FR.UTF-8 grep '^\s*' user@sid:~$ echo 'whatever you want' | LC_CTYPE=it_IT.UTF-8 grep '^\s*' user@sid:~$ # and so on More: user@sid:~$ locale -a | wc -l 462 user@sid:~$ for x in $(locale -a | grep '\.utf8$'); do echo 'foobar' | LC_CTYPE=$x grep '^\s*'; done | wc -l 0 user@sid:~$ for x in $(locale -a | grep -v '\.utf8$'); do echo 'foobar' | LC_CTYPE=$x grep '^\s*'; done | wc -l 174 Also note that the command behaves as expected if '^\s*' is replaced by '^[[:space:]]*' or '^[[:blank:]]*' or '^[ ]*', or if \s is not at the beginning of the regex.
