Is it documented anywhere what the allowed chars are..?
(I couldn't find it anywhere but sources :)

Hi,
unserialize() cannot unserialize objects whose names contain anything except
a-z, 0-9 and _, the parser allows those, though.
Example
=======
$ cat unserialize.php
<?php
class Über { }
var_dump(unserialize(serialize(new Über())));
?>
Expected behaviour
==================
$ php unserialize.php
object(über)(0) {
}
Actual behaviour
================
$ php unserialize.php
bool(false)
PHP Notice: unserialize(): Error at offset 5 of 15 bytes in
F:\Programme\cygwin\home\thekid\unserialize.php on line 4
Cause
=====

=1.40&r2=1.41&ty=u
Fix
===
Allow anything the parser allows, [a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*
