Re^6: How to display an apostrophe in pod2usage help output.

So based on what you have already told me, this seems to work. Is this safe?

if ( $help ) {
    $lang = $ENV{'LANG'}; $ENV{'LANG'} = 'C';
    pod2usage(-verbose => 2 );
    $ENV{'LANG'} = $lang;
}

After all this is over, all that will really have mattered is how we treated each other.

That will work given your current situation. Two problems: 1. it won't fix any problems with other programs (like man) that look at the locale to determine the encoding. 2. if someone does set their terminal encoding to utf-8 (or uses another terminal that defaults to utf-8, which the systems local terminals almost certainly do) it will mess up 8-bit "extended ascii" characters (like latin-1, or whatever the system ~~thinks~~ uses by default). IOW, you're almost certainly better off in the long run if you configure the terminal(s) to use UTF-8. Unless you're 100% sure you're never going to have to read anything but latin-based characters - or perl 6. Then you could just set the systems' default LANG to C instead of hacking around the problem by ignoring the locale. "What should it profit a man, if he should win a flame war, yet lose his cool?"
