This function is used under rare circumstances. It is necessary only when running non-UNICODE applications that must deal with text (for example, filename strings) that is not part of the ASCII character set (for example, Japanese characters). Non-ASCII text (i.e. a Japanese or Arabic character) can be stored non-ambiguously in UNICODE. However, for non-UNICODE applications, the multi-byte representation of such characters depends on the code page. In this case, you must set the code page appropriately. For example, a non-UNICODE application can display Japanese characters only if the code page is set to a Japanese code page (like Japanese_Japan.932).
Pass NULL for the parameter locale to get the current locale, leaving the current locale unchanged.
Internally, this function calls the Microsoft C runtime function, setlocale. For details, see the MSDN documentation.
