If the function succeeds, cchData is nonzero, and LOCALE_RETURN_NUMBER is specified, the return value is the size of the integer retrieved in the data buffer; that is, 2 for the Unicode version of the function or 4 for the ANSI version.

And a quick test shows that the call to GetLocaleInfoW succeeds with
cchData=2 on both Windows and Wine, but GetLocaleInfoA with cchData=2
fails on both Windows and Wine.
