All, I have managed to fix my problem with the special characters. Conversion to ASCII can be accomplished by including the following. # Convert plus's to spaces $parseString =~ s/\+/ /g; # Convert %xx URLencoded to equiv ASCII characters $parseString =~ s/%(..)/chr(hex($1))/ge; Browsers don't display "<" chars as it could represent a tag in html. To get round the problem, you need to do the following conversion for the 'main' special characters in HTML. # Convert < > & " to 'html' special characters. $parseString =~ s/&/\&/g; $parseString =~ s/</\</g; $parseString =~ s/>/\>/g; $parseString =~ s/"/\"/g; < < (less than sign) > > (greater than sign) & & (The ampersand sign itself) " " (double quote) FYI more info on special characters can be had here http://www.sandia.gov/sci_compute/symbols.html Cheers, Dave.
