DB Collation Issue

[Debojyoti Chattopadhya]

Hi

I am working on a Internationalization project and database I am using as mysql. The problem is I need a db collation like utf8_bin + ci

Example :

Table name : Test
Field names : id, keyword, status


here the keyword field collation should be
case insensitive and accent sensitive + it should be unique

Can you please help me here what should I do ?
If I need to create any custom collation in that case how to do that ? Can you send me some details.
