That seems like a roundabout way of doing it. Wouldn't cpinfo.MaxCharSize == 2 work as well? -- Alexandre Julliard julliard(a)winehq.org

Yes, it would. The docs warn against relying on MaxCharSize, but I don't see any reason that would affect this usage. "The function cannot use the size to distinguish an SBCS or a DBCS from other character sets because of other factors, for example, the use of ISCII or ISO-2022-xx code pages."
