Some languages - like the hungarian - have some characters, that naot correctly rewtited by the friendly url script.
 
The list:
? - e
? - i
? - o
ő - o
? - u
? - u
 
Can you implement this characters?

So I can post You the special characters, that is not displayed correctly in the post too...

Ok, I've searched for infos and found this:
# Internal Function
MapType: int, MapSource: Internal Apache function
 
Here the source is an internal Apache function. Currently you cannot create your own, but the following functions already exists:
 
* toupper:
Converts the looked up key to all upper case.
* tolower:
Converts the looked up key to all lower case.
* escape:
Translates special characters in the looked up key to hex-encodings.
* unescape:
Translates hex-encodings in the looked up key back to special characters.
 
Maybe the last functions could make a goog rawrited url for every hungarian characters...
