Description Joe Orton 2004-11-10 14:54:58 UTC 
Is this some weird UTF-8 thing or am I being stupid?  Stock FC3 grep:

$ rpm -q grep
grep-2.5.1-31.i386
$ cat out
         U CRYPTO_add_lock
         w __cxa_finalize
         U d2i_PrivateKey
         U d2i_PrivateKey_bio
$ grep ' [A-TV-Z] ' out

Actual behaviour:

$ grep ' [A-TV-Z] ' out
         w __cxa_finalize
$

Expected behaviour as per LANG=C

$ LANG=C grep ' [A-TV-Z] ' out
$
Comment 1 Tim Waugh 2004-11-10 15:11:42 UTC 
It's not UTF-8 but locale collation order.  Try LANG=en_GB, for example.

For the particular case you're after I think it's most portably
described by ' [ABCDEFGHIJKLMNOPQRSTVWXYZ] ', believe it or not.

See 'man grep', "Regular Expressions", paragraph 5.
