My error!

The problem was not in the Name Class which is perfectly suitable for
its purpose. The error was in using it for something which in the RFC is
defined as a character-string.

The solution was of course to define a new class (Charstr) and to give
it the appropriate implementation.

If anyone wants the fix I can send you a diff.
