There is no way _we_ can correct Firefly's pixmap font.  GPL requires
all derived work to be GPL, too.  The only way to solve this license
conflict is to persuade Firefly to change the license on dual-license
his pixmap work.

The discussion was in Firefly's own forum, and it is in Chinese:

Reading this thread, my impression is that Firefly isn't interested in
license himself, and I suspect (with all respect) he doesn't know much
about license issues.

Exactly.  Firefly claims his pixmap fonts to be under GPL.  However he
is distributing the ``firefly new sung'' font including Arphic's
vectorized fonts and his pixmap fonts.  This is in violation of both APL
and GPL.  Such a font is undistributable, let alone in Debian.

How can we achieve this without persuading Firefly?

You can't take Firefly's GPLed pixmap fonts and relicense it under APL
unless Firefly relicense it.  This is in violation of GPL.

Yes I am aware that APL is DFSG-free.  I was talking that a font mixed
of APL and GPL parts is _undistributable_.  I know in this case the
upstream author doesn't care about license, but it's a Debian
maintainer's resposibility to check these issues.

If necessary, I can write a mail in Chinese to Firefly (I hope he reads
simplified Chinese).  But I hope the maintainer who proposed ITP is
aware of this issue.  And since I had no contact with Firefly before,
it's probably better for someone else he knows to raise this issue to
him.  After all, many developers hate license issues.

I hope I made myself clear.
