GetACP

• [https://msdn.microsoft.com/en-us/library/windows/desktop/dd318070(v=vs.85.aspx MSND - GetACP]
• Stackoverflow - How can I programmatically determine the current default codepage of Windows?

Retrieves the current Windows ANSI code page identifier for the operating system.

Caution

The ANSI API functions, for example, the ANSI version of TextOut, implicitly use GetACP to translate text to or from Unicode. For the Multilingual User Interface (MUI) edition of Windows, the system ACP might not cover all code points in the user's selected logon language identifier. For compatibility with this edition, your application should avoid calls that depend on GetACP either implicitly or explicitly, as this function can cause some locales to display text as question marks. Instead, the application should use the Unicode API functions directly, for example, the Unicode version of TextOut.

GetOEMCP

• [https://msdn.microsoft.com/en-us/library/windows/desktop/dd318101(v=vs.85.aspx MSDN - GetOEMCP]
