Hello,
Sorry to hear of your problems searching for Chinese words in your glossary.
The problem of only having one alphabet for browsing has been reported previously as MDL-22233. Please feel free to create a tracker account then you can vote for the issue to be fixed, and watch it to receive email notifications of updates.
I just tried adding a glossary entry including "你", then entered it as a search term. The entry was found. Thus it seems your problem is specific to your set-up.
I'm going to move this discussion to the Languages forum where lots of character experts hang out...
