However, the functions will always consult the config file to allow the
user-defined values override the default logic and there is no way to
disable this - which shouldn't be ever needed because if "interactive" was

In case everything else fails (i.e. there is no record in config file

the class queries \helpref{wxEncodingConverter}{wxencodingconverter}
for "equivalent" encodings (e.g. iso8859-2 and cp1250) and tries them.
