	LANG=de_DE.ISO_8859-1

>Description:

	regexp matching in awk/nawk:

	if (c !~ /[a-zA-Z]/)

	when var c is set to value "0++" or "000"
	c ~ /[a-zA-Z]/ results in 1
	c !~ /[a-zA-Z]/ results in 0

	like when c contains a normal word.

>How-To-Repeat:

	1)
	simple test:

#!/usr/bin/awk
/[a-zA-Z]/ {
        print "Has a Letter: " $0
}
/[A-Z]/ {
        print "Has a big Letter: " $0
}
/[a-z]/ {
        print "Has a small Letter: " $0
}

	every String matches the first and third command.

samples:

Has a Letter: 
Has a small Letter: 
1
Has a Letter: 1
Has a small Letter: 1
a
Has a Letter: a
Has a small Letter: a
A
Has a Letter: A
Has a big Letter: A
Has a small Letter: A
C
Has a Letter: C
Has a big Letter: C
Has a small Letter: C
Z
Has a Letter: Z
Has a big Letter: Z
Has a small Letter: Z
]
Has a Letter: ]
Has a small Letter: ]



	2)
	start regression test (without install) in:
$ cd /usr/porst/news/cnews && make
$ cd /usr/porst/news/cnews && make test

	output:

: namecheck.awk
test " `echo | awk -f namecheck.awk`" = " empty name" ;
test " `echo a b | awk -f namecheck.awk`" = " white space in name" ;
test " `echo 'a b' | awk -f namecheck.awk`" = " white space in name" ;
test " `(echo a ; echo b) | awk -f namecheck.awk`" = " newline(s) in name" ;
chmod +x namecheck.r
sed -n '/^[^#]/p' namecheck.t >tmp.nc
./namecheck.r <tmp.nc
comp.lang.0++:
saw:
not:    name component does not contain letter
*** Error code 1

Stop in /home/image/usr/ports/current/cnews/work/util.
*** conf/inall terminated

>Fix:

	workaround:

	unset LANG:
$ export LANG=
