Package: grep
Version: 2.5.1.ds2-5
Severity: normal
I noticed that enabling --ignore-case suddenly caused certain patterns
not to match any longer although they should:
$ echo 'foo bar' | grep '^foo\W'
foo bar
$ echo 'foo bar' | grep -i '^foo\W'
$
Digging further reveals that there's an locales influence since
$ echo 'foo bar' | LANG=C grep -i '^foo\W'
foo bar
$
matches again. After a check using all my generated locales:
MATCH:
- de_DE
- de_DE@euro
- en_US
FAIL:
- de_DE.UTF-8
- de_DE.UTF-8@euro
- en_US.UTF-8
there's a strong impression that UTF-8 locales somehow disturb \W when
using -i.
Even more confusing, using the bracket expression instead of the synonym
matches again:
$ echo 'foo bar' | LANG=de_DE.UTF-8 grep -i '^foo[^[:alnum:]]'
foo bar
$
For the records, this sounds somewhat similar to #209194 and #218873 but
these bugs are fixed in this version (2.5.1.ds2-5), I've checked.
By the way, there's a typo in the manpage
and
.B \eW
is a synonym for
- .BR [^[:alnum]] .
+ .BR [^[:alnum:]] .
.PP

Hi,
I'm closing this bug since the issues with character classes and cases
ignored in multi-byte locales was fixed in grep 2.6.
$ echo 'foo bar' | LANG=C grep '^foo\W'; echo $?
foo bar
$ echo 'foo bar' | LANG=es_CO.UTF-8 grep '^foo\W'; echo $?
foo bar
0
Regards,
Santiago
