Description Robert Scheck 2004-05-17 17:48:59 UTC 
Description of problem:
UTF-8 enabled:
--- snipp ---
[robert@tux robert]$ export LANG=de_DE.UTF-8      # this is also RH default
[robert@tux robert]$ echo Y | grep -i '[y,Y]'
[robert@tux robert]$  
--- snapp ---

UTF-8 disabled:
--- snipp ---
[robert@tux robert]$ export LANG=de_DE.iso88591   # alternative: de_DE@euro
[robert@tux robert]$ echo Y | grep -i '[y,Y]'
Y
[robert@tux robert]$  
--- snapp ---

The behaviour without (!) UTF-8 is correct...so there's something
going wrong :-(

Version-Release number of selected component (if applicable):
grep-2.5.1-7 (and maybe before, too) up to grep-2.5.1-26

How reproducible & Steps to Reproduce:
Everytime, see above.

Actual results:
It seems so, that there's a problem at grep using UTF-8...for 
debugging I attached you two strace logs.

Expected results:
Using "echo Y | grep -i '[y,Y]'" with any locale and charset ;-)

Additional info:
This issue is also affected to Fedora Core 1, Fedora Core 2 and
Red Hat Enterprise Linux 3, I only reported it to Fedora Core devel,
because it's the active development tree.
