String encoding in extension API

Hi there, I'm updating pecl/fribidi to use zend_parse_parameters() instead of the ancient zend_get_parameters() and I'm not sure what encoding expect from zpp() when I ask for a string value with non-ascii characters. Is there any conversion done mechanically? Also, when I call RETURN_STRINGL with some UTF-8 encoded data, I get a double-encoded string in my script. Again, what's the expected encoding for calling RETURN_STRINGL()? Would appreciate any hints, -Behnam -- Behnam Esfahbod | بهنام اسفهبد http://behnam.es/ GPG-FP: 3E7F B4B6 6F4C A8AB 9BB9 7520 5701 CA40 259E 0F8B
