Defines the locale, the country, region, and language to use when translating wide-character constants and string literals.

#pragma setlocale( " [ locale-string ] " )

Because the algorithm for converting multibyte characters to wide characters may vary by locale, or the compilation may take place in a different locale from where an executable file will be run, this pragma provides a way to specify the target locale at compile time. It guarantees wide-character strings are stored in the correct format.

The default locale-string is "".

The "C" locale maps each character in the string to its value as a wchar_t. Other valid values for setlocale are the entries found in the Language Strings list. For example, you could specify:

#pragma setlocale("dutch")

The ability to specify a language string depends on the code page and language ID support on your computer.
