Cygwin generally handles filenames with colons just fine, by mapping the
character to some higher Unicode character and remapping on the fly.
However Cygwin's `unzip` appears to have a bug: when unzipping an
archive that contains a filename with a colon, it replaces the colon
with an underscore.
cygcheck.out and simple test script attached; expected behaviour from
running `bash unzip-bug.sh` is that you get an empty file called `a:b`,
but on Cygwin you instead get an empty file called `a_b`.
It's an explicit #ifdef __CYGWIN__ in upstream unzip, file unix/unix.c,
which transforms a bunch of characters.
If I uncomment most of them (except \), all unpack fine:
x0:z x1<z x2>z x3|z x4"z x5?z x6*z
Someone should report upstream please.
