Hi everyone, I'm doing some simple translation of LaTeX for the web, and am writing a simple translator to turn a (very small) set of symbols into html entities. We want our database to store html entities instead of unicode, so I'm doing this in ASCII. Here's a copy of my translation: 

my %allowed_text_code = ('$\\alpha$'     => 'α',
                         '$\\beta$'      => 'β',
                         '$\\gamma$'     => 'γ',
                         '$\\delta$'     => 'δ',
                         '$\\theta$'     => 'θ',
                         '$\\pi$'        => 'π',
                         '\\degrees'   => '°'
                         );

and the regular expression I'm using later on: 
 foreach $tex_key (keys %allowed_text_code){
        $text =~ s/\Q$tex_key\E/$allowed_text_code{$tex_key}/g;
        print $text. "\n";
        }

I've only tested the '$\\pi$' tag, and whenever I look at the resulting file, I'm getting a carriage-return character and a script f ('¶ƒ' on OS X, in TextWrangler). On the web, I'm getting '¦Ä'. So does anyone have any idea what the encoding issue is? Ideally, I would like the output file to be in strict ASCII so that this problem doesn't arise, or do I need to escape my values in my regular expression, or what is it I'm missing here?
