Case insensitivity seems to ignore lower bound of interval

[Eric Bischoff]

Hi all,


$ echo "ijklmnopqrstuvwxyz" | awk '{ gsub(/[R-Z}/, "X"); print }
ijklmnopqrXXXXXXXX

please notice that "r" is not matched, i.e. case insensitivity is applied only 
to [S-Z] interval.

$ awk --version
GNU Awk 3.1.7
(...)

$ echo $LANG
fr_FR.UTF-8

The problem does not appear when locale is C.

The problem does not appear when interval is specified as [r-z] (lower case)..

This contradicts http://www.gnu.org/software/gawk/manual/gawk.html#Locales
which documents 
     $ echo something1234abc | gawk '{ sub("[A-Z]*$", ""); print }'
as returning
     something1234
while it returns
     something1234a

Bug reproduced both on Ubuntu Natty beta 2 and on Fedora 15.


I hope that helps,
