Setting $MakePageNameFunction to an empty string causes it to
use PmWiki's built-in MakePageName function.  The built-in uses
PHP's strtoupper() function, which doesn't know what to do with
UTF-8 characters.

So, if you're willing to live with PmWiki being unable to properly
uppercase non-ascii first letters of words in pagenames, it's 
probably okay.  But it means that something like [[édition]] would
result in an invalid pagename, because (in UTF-8) strtoupper()
doesn't know how to convert the "é" into an uppercase equivalent.

I've been thinking about adding a special-purpose UTF-8 capable
"strtoupper" function to be used in the xlpage-utf-8.php script,
to be able to avoid the need for the mbstring functions altogether.
I'll be glad to work on that now if you're willing to help test
it... :-)
