fulltext search using different collation

[tdolfo]

Hello all,
I'm running MySQL 5.0.41. I have a table with its charset set to utf8,
collated to utf8_bin. I'm using utf8_bin because I need case-sensitive
unique values in a specific column. I'd like to perform a case-
insensitive fulltext search on this particular column. I've created a
fulltext key, however I cannot seem to change the collation for the
search. I see no docs on the MySQL website either (however I did find
this, which may be useful to some:

http://dev.mysql.com/doc/refman/5.0/en/charset-collate.html).

Ultimately, I need inserts to be case-sensitive for uniqueness, but
fulltext searches to be case-insensitive. I've included my test table
creation statement. Any help would be appreciated.

Thanks,
TD
