I run tnefparse in command line with debug mode: tnefparse winmail.dat -l DEBUG

It seems like the encoding charset is wrong, is that anyway to set the charset as parameter?

You can have different codecs nested in different parts of the document. We could probably have a universal override but that probably cause other problems.

What about returning the raw bytes when rather than an exception in the case of decoding error?

@aniude are you able to share an example tnef that generates this error?
