[vwnc] DefaultEncoder in Filename not threadsafe

[Terry Raymond]

The DefaultEncoder shared variable in Filename is an
EncodedStream. Being that it is mutable and not protected
it is not threadsafe.

As a general rule, mutable singletons are not threadsafe
and should be either be eliminated(preferable) or protected.
