This section describes the features available in Microsoft® SNA Server for supporting international languages and different national language character sets. Introduced with SNA Server version 3.0, the SNANLS API available on Microsoft® Windows NT® and Microsoft® Windows® 95 can be used to support international languages in SNA applications by means of a standardized and consistent interface. The SNANLS API uses the language support features provided with Windows NT and extends these same features to Windows 95 clients. SNANLS supports European languages that use single-byte encoding as well as far eastern languages that use double-byte or Unicode encoding.
In Windows 3.x and Microsoft® MS-DOS® environments where SNANLS is not supported, developers can use the TrnsDT API for supporting Far Eastern languages such as Japanese, Korean, and Chinese, and Windows code page support for single-byte conversions.
