[ID 20000903.001] \w in utf8-strings

This is a bug report for perl from root@cerebro.laendle,
generated with the help of perlbug 1.32 running under perl v5.7.0.


-----------------------------------------------------------------
[Please enter your report here]

while debugging PApp for days since switching to utf8, I stumbled over yet
another problem:

\w doesn't include _ when utf8 is in effect:

# perl -e '"alpha_numeric" =~ /(\w+)/ and print $1'
alpha_numeric

# perl -e 'use utf8; :~# perl -e '"alpha_numeric" =~ /(\w+)/ and print $1'
alpha

[Please do not change anything below this line]
