Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14

Bugzilla 3.0.3 with Perl 5.8, Windows 2003. UTF8 support is switched on. 

Bugzilla wraps comments with multibyte utf-8 symbols as text with only one-byte ascii symbols.

You can see that in the https://bugzilla.mozilla-russia.org/ comments are half shorter then in the https://bugzilla.mozilla.org.

Reproducible: Always

Steps to Reproduce:
1. Write any comment with more then 40 russian symbols. 
2. Open the bug in a browser

Actual Results:  
All comment's lines will be wrapped at about COMMENT_COLS / 2 columns.

Expected Results:  
Comment's lines should have length of no more then COMMENT_COLS columns.

Simple workaround is to turn on the UTF-8 flag in $comment variable in function wrap_comment (file Bugzilla\Util.pm).

sub wrap_comment {
    my ($comment) = @_;
    my $wrappedcomment = "";

    Encode::_utf8_on($comment);
    # Use 'local', as recommended by Text::Wrap's perldoc.
...
...
    Encode::_utf8_off($wrappedcomment);

    return $wrappedcomment;
}

This problem is fixed in Bugzilla 3.2. No backport is planned on 3.0 due to heavy changes it involves. As a workaround, you could increase the value of COMMENT_COLS in your installation. This would be a problem if someone types a comment in ASCII, though, as the comment would be too large. Maybe try to find an acceptable value for COMMENT_COLS considering both testcases?
