Bash Version: 4.4
Patch Level: 0
Release Status: release
Description:
It seems like bash built-in regex matches some symbols that shouldn't.
The following commands shows this:
[[ 'º' =~ [o-p] ]] && [[ ! 'º' =~ o ]] && [[ ! 'º' =~ p ]]
&& echo 'º between o and p but none of them'
[[ 'ª' =~ [a-b] ]] && [[ ! 'ª' =~ a ]] && [[ ! 'ª' =~ b ]]
&& echo 'ª between a and b but none of them'

Actually found out this while developing a bigger bash script, but it
can be reproduced with the previous lines. Would you reply me at
amatba...@gmail.com to know if this was in fact a bug? Thanks.
