You could transform the search string into a regex that matches the unicode and non-unicode characters.

For example:

With these documents:

> db.t38528.find()

{ "_id" : ObjectId("52d6553a46fc814f046fa733"), "text" : "Tôi yêu cộng đồng Mongodb" }

{ "_id" : ObjectId("52d656d146fc814f046fa735"), "text" : "yeu cong dồng" }

This query will find any mix of unicode/non-unicode:

> db.t38528.find({text: /c(ộ|o)ng (đ|d)(ồ|o)ng/i })

{ "_id" : ObjectId("52d6553a46fc814f046fa733"), "text" : "Tôi yêu cộng đồng Mongodb" }

{ "_id" : ObjectId("52d656d146fc814f046fa735"), "text" : "yeu cong dồng" }
