Description

Attempting to build the editor from source will fail to compile in VS if the computers Region format / Language is set to Turkish. This is caused by #ifndef Identifiers being translated incorrectly. The "I" (capital "i" ) is being read as a different character ("İ").

Example in CorePrivePCH.h:

correct format - #ifndef AUTO_COREPRIVATEPCH_H_
incorrect format (set lang to Turkish) - #ifndef AUTO_COREPRİVATEPCH_H_

Steps to Reproduce
  1. Open Control Panel->Clock, Language, and Region->Language and Region
  2. In the Formats tab set the Format drop down to Turkish (Turkey)
  3. In the Location tab set the Current Location to Turkey
  4. Run Setup.bat and GenerateProjectFiles.bat
  5. Open UE4.sln and build

Result:
Build will fail to compile due to Identifier errors
