This document is a companion reference to the protocol specifications. It describes how Unicode strings are compared in Windows protocols and how Windows supports Unicode conversion to earlier codepages. For example:
UTF-16 string comparison: Provides linguistic-specific comparisons between two Unicode strings and provides the comparison result based on the language and region for a specific user.
Mapping of UTF-16 strings to earlier ANSI codepages: Converts Unicode strings to strings in the earlier codepages that are used in older versions of Windows and the applications that are written for these earlier codepages.
