Thank you for response.
My issue is not related with similarity of l and I. That is about two letters – “i” and “ı” which are identical but one without the dot above. Same like o and ö. Due to in English small letter “i” doesn’t have dot when it is used as capital (I), but in that particular language the dot is used (İ), cause the the letter I – without dot is different oneş
So to be short in my language forms of small and capital are such:
i – İ
ı – I.
But in theme while capitalizing both of small letters appear as I. So I am looking to overcome this.
