Module      -  UString.hpp
System      -  Common
Author      -  Tom Bernhardt, Rich Denham
Created     -  1995-08-25
Description -  Common string and character functions.
      Many string and character functions defined in "string.h" are redefined
         here as overloaded inline functions with several extensions:
      o  Both ANSI and UNICODE strings are supported.
      o  Both ANSI and UNICODE characters are supported.
      o  For ANSI, characters can be "char signed" or "char unsigned".
      o  Functions that allow a length field, such as "lstrcpy" vs "lstrcpyn",
         are implemented as overloaded functions with optional arguments.
      o  Some functions, UStrCpy in particular, can perform conversion between
         ANSI and UNICODE strings.
      The function names defined here consist of "U" concatenated to the base
         name from "string.h".  The first letter of words or word abbreviations
         are capitalized, e.g. "strcpy" becomes "UStrCpy".
