I consider it a bug but it is designed into it.
For some reason it allows validates names for DOS but later versions
Windows are less restricted in the characters that can be used - almost
anything other than |<>:*? and characters [#0..#31]. (actually Windows
itself is more restricted than the underlying file system which does not
make much sense).
I do know when compressing it checks some properties of the source drive
so, in theory at least, extract should be able to adapted - I will see
what I can do.
I personally don't like replacing illegal characters with '_' , I think
it would be better to handle it similar to URLs - replace with an escape
sequence %nn (nn is decimal 'value' of the character).
