Problem

The issue is letter I and i is different in Turkish but as we all know that is not the case in english. And any programing language is desinged English in mind. Therefore, we need this fix to become how ecmascript should work or better form of this must.

Getting started.

Place the file before other scripts

Turkish toLocaleLowerCase

var text = "İstanbul";
text.toLocaleLowerCase("tr-TR"); // istanbul
