 # Using generic-text mappings
 
 **Microsoft Specific**
 
-To simplify code development for various international markets, the Microsoft run-time library provides Microsoft-specific "generic-text" mappings for many data types, routines, and other objects. These mappings are defined in TCHAR.H. You can use these name mappings to write generic code that can be compiled for any of the three kinds of character sets: ASCII (SBCS), MBCS, or Unicode, depending on a manifest constant you define using a `#define` statement. Generic-text mappings are Microsoft extensions that aren't ANSI compatible.
