Package: locales Version: 2.28-10 Severity: normal Tags: l10n Dear maintainer!
I'm not positive that this is a bug (the man page for grep does warn about character ranges in locales other than C) but it produces very surprising results in grep. Presumably this is realated to bugs #506784 and #511357. % echo -n abcdefghijklmnopqrstuvwxyz| sed 's/./&\n/g'| LC_COLLATE=C grep '[a-z]' a b c d e f g h i j k l m n o p q r s t u v w x y z % echo -n abcdefghijklmnopqrstuvwxyz| sed 's/./&\n/g'| LC_COLLATE=sv_SE grep '[a-z]' a b c d e f g h i j k l m n o p q r s t u v x y z % : Note the lack of 'w' above. % LC_COLLATE=sv_SE grep '[a-w]' grep: Invalid range end % : This time at least there was an error message to warn me about the problem. As i typically write "[a-z]" as shorthand for "[[:lower:]]" when i don't need to match any national characters this bothers me quite a bit. -- System Information: Debian Release: 10.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-6-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=C, LC_CTYPE=sv_SE.utf8 (charmap=UTF-8), LANGUAGE=C (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages locales depends on: ii debconf [debconf-2.0] 1.5.71 ii libc-bin 2.28-10 ii libc-l10n 2.28-10 locales recommends no packages. locales suggests no packages. -- debconf information excluded
