I and my friends are in the process of creating the Georgian (ka_utf8) language pack for Moodle. One of the problems we had was the grouping for concepts, defined in utf8. I made some changes in view.php of Glossary module which should not affect users who do not use utf8. Attached are problem screenshots and diff file for view.php. It might be useful for other people who use UTF8 in glossaries.
Some questions; is there any changes planned to make this module friendlier for Unicode and particularly for utf8? Any experience using mbsring functions in moodle? Should we use function overriding in php.ini? Thanks in advance.
