I've made an improvment to glossary module, http://moodle.org/mod/forum/discuss.php?d=24114 , which lets glossary can index non-ascii charset. It is very important to non-latin languages. But I met some problems and needs your help.
I want to make the code more general and can be merged into moodle CVS smoothly. It must be very proud thing. In my implementation, I used database subquery which is supported since MySQL 4.1. So, it's not general,
The index of A-Z is easy to implement without subquery. I've test codes about it. But for special chars index, there should be more modification (even impact the code structure) if we don't use subquery. How to avoid it? I can't find the way and need your help.
Thank you.
