I can confirm this.

It is the magic of Python. This patch should fix the issue.

I can also confirm this bug, but the patch above fixes it.

Thanks Serguey. I've applied this upstream and will get this into maverick.

This bug was fixed in the package ufw - 0.30.0-1ubuntu1

---------------
ufw (0.30.0-1ubuntu1) maverick; urgency=low

  * src/frontend.py: display unicode error messages properly. Thanks to
    Serguey Basalaev.
    - upstream commit r700
    - LP: #580032
  * src/backend_iptables.py: fix gettext warning
    - upstream commit r701
  * run debconf-updatepo, but adjust debian/po/de.po and debian/po/es.po to
    add correct "Language:" tag
  * profiles/ufw-mailserver: remove Postfix specific language
    - upstream commit r705

ufw (0.30.0-1) unstable; urgency=low

  * New upstream release. Use 0.30.0 as the version even though upstream uses
    0.30 in order to sync to Ubuntu. Fixes:
    - LP: #568877
    - LP: #611982
    - LP: #606997
    - LP: #624199
    - LP: #625340
    - LP: #521359
    - LP: #436608
  * don't flush chains if ufw is not enabled (LP: #581744)
  * debian/postinst: don't source /usr/share/debconf/confmodule when $1 =
    triggered. Fix thanks to Colin Watson. (LP: #618410)
  * debian/control:
    - drop versioned depends on iptables. This helps with backporting now that
      the test suite can handle it
    - updated Standards-Version
  * debian/rules:
    - pass interpreter to run_tests.sh
    - don't install upstream application profiles for now
  * add rsyslog support
  * add debian/source/format
  * debian/before6.rules.md5sum: updated for ucf

ludo33200, it is not fixed in Ubuntu 10.04, but in Ubuntu 10.10. I have added a task to do an stable release update for Lucid.
