Internal Variables:

These variables return the remapped, “safe” values for various characters. They can be used to search for or replace the remapped characters in functions such as @INDEX and @REPLACE. If the //UnicodeOutput option is set to NO, then these remapped characters can also be redirected to a file, and TCC’s built-in Unicode-to-ANSI translation will automagically replace them with the “dangerous” forms.
