That is neat, but you'd also need to s/// ascii codes like:

and no doubt lots of other tricks. It's generally better to strip everything out than to try and keep up with the kids, i've found.

update: completely wrong, as jeffa was tactful enough to point out privately. the translation of the ascii character happens in perl, not in the browser. i tested with a qq|| string and didn't look at the html source. slap.
