Tcl_Backslash - parse a backslash sequence

       const char *src (in)         Pointer to a string starting with a backslash.

       int *countPtr (out)          If  countPtr is not NULL, *countPtr gets filled in with number of characters
                                    in the backslash sequence, including the backslash character.

       The use of Tcl_Backslash is deprecated in favor of Tcl_UtfBackslash.

       This is  a  utility  procedure  provided  for  backwards  compatibility  with  non-internationalized  Tcl
       extensions.   It  parses  a  backslash  sequence  and  returns  the  low  byte  of  the Unicode character
       corresponding to the sequence.  Tcl_Backslash modifies *countPtr to contain the number of  characters  in
       the backslash sequence.

       See  the  Tcl  manual  entry  for  information  on  the  valid backslash sequences.  All of the sequences
       described in the Tcl manual entry are supported by Tcl_Backslash.
