I think, legitimate cases when zero-width spaces should be preserved in 
a document may exist, so unconditionally stripping them is not a perfect 
solution.

I am afraid, regexps detecting start and end of emphasis are similar to 
a short blanket. They will always fail for some cases, especially since 
verbatim, URLs and similar contexts (that significantly differ from 
prose in respect to punctuation) do not have higher priority for parser.

Extensive test set is required for tuning of heuristics. Failures should 
be reported in a such way that allows to estimate overall quality before 
and after change. Ideally, format of file with such tests should allow 
to use the *same* input data for other tools like ruby-org.
