case insensitivity & Turkish character filtering problem with mongodb about fop

[VitorCorrei4]

For the filter :
The "I" character you provided from "MAVİ GİYİM A.Ş." it's not a I (ascii 073)
MAVİ its diferente from MAVI

For case sensitive a workaround would be to use lowercase for data and filter

unfortunately, turning it to lower case does not solve the problem in our case,
I need help for something like this
lower case i --> uppercase İ
lower case ı --> uppercase I

[VitorCorrei4]

It looks to me like a formatting problem, anyway it looks weird for both examples on the first
lower case i --> uppercase İ
the uppercase char (İ) is a different letter than the uppercase of "i" (ASCII : 105)
and on the other :
lower case ı --> uppercase I
also, those are diferent letters
Anyway, being case sensitive is a feature of the lib, as a last resource you can always use "string.ToUpper().ToLower()" to trying to force the string without special characters, or an extension method on string.
