Mismatched character alignment in text processor hook `GetTextExtentExPointA` #8

The current implementation of the GetTextExtentExPointA hook simply converts to utf16 and forwards it to GetTextExtentExPointW. This is incorrect if used with MBCSs since it assumes each character's index to equal its byte offset.
