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.
Syntax
UINT GetACP();
Return value
Returns the current Windows ANSI code page (ACP) identifier for the operating system. See Code Page Identifiers for a list of identifiers for Windows ANSI code pages and other code pages.
Remarks
The ANSI code pages can be different on different computers, or can be changed for a single computer, leading to data corruption. For the most consistent results, applications should use UTF-8 or UTF-16 when possible.
