Hi Marcos, >>Unless it's broken (?), I would prefer to leave it as is. I think that P&C should either change the grammar (as suggested in my email) or specify that the zip-rel-path operates on characters. The first would be well adjusted to Zip filename encoding in UTF-8 as a kind of natural match, whereas the latter could be clearer wrt the characters that can be used in the path.
Anyway, I think some clarification - e.g. on of the above - is required. Thanks.
