Re: [Fwd: Droid fallback CJK and fontconfig?]

hi Nicolas

As we discussed last time, I've sent email asking for official confirmation
and clarifications of the license in the font metadata. I am now waiting
to hear back from them (message attached).

The Han glyphs in Droid fallback pretty much follow the Han-unification
as in the unicode documentations. That means they look very much close
to what Chinese mainland users preferred. The style is Heiti, which is like
ttf-wqy-zenhei and is essentially a sans-serif style. There are 16,502 Hanzi
in the CJK basic block, which is the union of GB2312 and Big5 charsets.
Because this font is targeted at memory-limited devices, there are
15,524 Han glyphs were composed by references, the rest are stand-alone
outline glyphs which can not be decomposed into components.
It contains no embedded bitmaps, but the outline quality is very good.
I believe most zh_* users will be very happy if this font will be used
as desktop font (the current zh_* font on Fedora is wqy-bitmapfont
which is also using the Han-unification forms). It may be a little bit
difficult for Japanese and Korean users though.

As this font does not provide the full coverage to all CJK glyphs,
in the mean time, I believe the current national standards and
regulations in mainland China prefer GBK (same as CJK unified ideographs),
or even GB18030 (CJK basic+CJK Ext. A) coverage, so, I've planned to extend
this font to at least GBK charset. That means to complete about 4500
glyphs. I and a friend are now working on an online tool to allow
people to compose new glyphs from existing Droid components.
It is almost working, you can browse the following link for a sample
output: (need to view with firefox 3.x)

the GUI is at
but it only has Chinese instructions so far.

Once the license is sorted out, we will start promoting this project
among the Chinese users, and make our way toward a more complete
CJK font with this extension. I also planned to look into the reference
glyphs and seek the possibility of further compression of the font.
Similar to the current ttf-wqy-zenhei settings, Chinese users will also be
happy to see a mono-spaced face co-existing with the regular face in
ttc form.

Hi Qianqian,

I'll follow up with the people responsible for fonts.

    hi Joe

    A few weeks ago, I posted a question on android-discussion group,
    asking about the droid font licenses:

    I really appreciate your feedback and confirmation on the license

    As I am an maintainer for an open-source font project, I also
    maintain a few CJKV font packages for Fedora. Recently, I
    mentioned my plan of making derived fonts from Droid
    font family at fedora's font list, the people in charge appeared
    to be very careful, and warned me to obtain a more "official"
    clarification on the license before taking further actions. You
    can see our discussions at

    We both felt that the best way to make the clarifications is to state
    it in the metadata section of the font, there are dedicated
    "License Description"
    and "License Info URL" fields in the name table to specify the
    font licenses:

    I am wondering if it is possible for android team to update the font
    files and clarify the licenses. In this way, people's confusion on
    the fonts
    and the sdk package will completely go away.

    If you or your team member do have the plan to make this
    change, I would be appreciated if you can let me know when
    the updated fonts are pushed into svn, so I can mobilize my
    team to start planned works around these fonts.

    thank you so much for your time and looking forward to your reply.

As you probably know Google has released a Droid font set as part of its
Android platform. While the font licensing is being clarified
(Fedora packaging blocker) I've taken a quick look at the font files.

The set includes a huge "Droid Sans Fallback" font with CJK coverage.
Could the CJK folks take a look at it and tell me how this font should
be treated: as Japanese-only, Chinese-only, Korean-only before/after
current CJK defaults, etc? Han unification means someone will probably
not be happy about it.

I've uploaded preliminary droid packages there

so people can check them out.
