[Bug 2070098] Re: zip buffer overflow detected with umlaut o (ö) in the filename

[Olivier Berger]

I think this is fixed in forecoming 3.0-14 on Debian... or linked to
some difference between Debian build and Ubuntu's

Just tested:
$ touch ö
$ LANG=C zip -9r o.zip ö
  adding: ö (stored 0%)

Without any crash...

Hope this helps,
