Trf_TransformCharacter - Interface to procedures for transformation of a single character.

       A  procedure  of  this type is called to encode/decode a single character. Return value is a standard tcl
       error code. In case of failure and interp not NULL an error message should be left in the result area  of
       the  specified  interpreter.  Only  one  of  'Trf_TransformCharacter'  and  'Trf_TransformBuffer' must be
       provided. This one is easier to implement, the second one should be faster.  If  both  are  provided,  ->
       'Trf_TransformBuffer' takes precedence.
