None.  ReadPage and WritePage are written such that whatever
you save with WritePage is exactly what you get back with ReadPage
(with the exception of certain values such as 'name', 'time', 'rev',

Yes.  WritePage will automatically convert the linefeeds to %0a,
and ReadPage will automatically convert them back to linefeeds.

If you mean a markup line break, then use "[[<<]]".

If you're wanting an end-of-line markup break, then use "\\\\",
which will end up being saved as two backslashes.  (The \ has
a special meaning to PHP, so two are required.)

It's not a problem with the way you're saving or retrieving
the characters; it has to be a problem with the way the markup 
rule is handling them (look for rules with /e flags at the end).

Either that or it's a problem with data coming from a form,
in which case you need to run stripmagic(...) on the form
values before using them.
