Remove charset conversion routines

This uses the AHK_L Unicode build, so strings are Unicode. (WStr / UTF-16)
See http://ahkscript.org/docs/Compat.htm#DllCall

Convert Russian translation to codepage 1251

Checking against the Russian.isl default translations, Cryllic script
uses the Windows 1251 codepage. The LangOptions section is copied from it.

pasting the source file into notepad, then back into Notepad++ with the
codepage set.
