Description

In Turkish, there are two I (dotless: ı, I and dotted: i, İ) Every time on Android after uppercase with CultureInfo an i, I get an I. On iOS everything works correctly.

Steps to Reproduce

2. Use method to upper case with Turkish CultureInfo (str1.ToUpper(new CultureInfo("tr-TR", false))
3. result is INDIGO instead İNDİGO
