New Comment:
This is because preg_replace() runs addslashes() internally on the captured
subpatterns before substrituting them into the replacement string. It didn't used to
but a few people complained that it was really hard to pass $n to a function because
of single and double-quote conflicts. To be frank, I'm not sure how to solve this
problem adequately, one group of people want the addslashes() run, the other one
doesn't.

Simple problem - the script:
<?php
echo preg_replace("/'/e", "\"$0\"", "'");
// that's double-quote, slash, single-quote, slash, e, double-quote
// then double-quote, escaped double-quote, $0, escaped double-quote, double-quote
// then double-quote, single-quote, double-quote
// meaning = "replace all occurrences of single-quote with the same string matched
during the search - i.e. single-quote"
?>
should produce one plain single-quote, but instead it produces an escaped
single-quote.
No other character seems to exhibit this behavior.
Configuration:
'./configure' '--prefix=/usr/local/php4' '--with-mysql'
'--with-apxs=/usr/local/sbin/apxs' '--enable-track-vars' '--with-gd=/usr/local'
'--with-zlib-dir=shared' '--with-ttf' '--with-jpeg-dir=/usr/local'
'--with-png-dir=/usr/local' '--with-tiff-dir=/usr/local' '--with-mcrypt'
'--with-pdflib'
No other unusual configuration setups
