I'll answer your questions from the point of view of cvs2git, a.k.a. cvs2svn (http://cvs2svn.tigris.org).

There is no builtin support for this in cvs2git. But the place where the author is determined knows about the whole changeset, including any simultaneous changes to the changelog. So it should be possible to add this functionality without too much work.

cvs2git allows you to specify multiple encodings. It tries one after the other until one works successfully. It also has hooks where you can add your own decoder using arbitrary Python code.

That reminds me that there is a Python universal decoder that uses heuristics to determine the encoding of an arbitrary octet stream. That might be a nice thing to add support for....
