The first of these has been significantly improved by disabling the
average-based subpixel filter
in app_server. The second turned out to be false -- while Noto has fonts for
any language, DejaVu
actually has support for a lot more languages in a single font (see commit
message). So that turned
out to not be true either, and having DejaVu be default with Noto available
in a package is a much
better solution.
If you know something I don't, please speak up.
Plain DejaVu: 242 languages according to
https://github.com/dejavu-fonts/dejavu-fonts/blob/master/langcover.txt
Plain Noto (without CJK - what we are using by default now): 583 languages
according to
https://www.google.com/get/noto/#sans-lgc ;
So even without the extra coverage of Noto CJK, etc, Noto is already 2x more
languages than DejaVu.
Also, this misses the point. The nice thing about Noto is that we can get a
common look for all locales. Not a single *font file*, but a single *look*. The
situation without Noto is that we have DejaVu, but also microhei (for Chinese)
and VL-Gothic (for Japanese), and should probably include more (for Korean,
etc). We can just include all the Noto fonts and be done with that.
The next step is to enable FontConfig and use it to select a font matching the
system language. Note that this is required either way: either we switch
between different Noto variants, or we switch between different fonts (DejaVu,
microhei, VL-Gothic). Except switching between different fonts looks ugly when
you mix Japanese and Latin characters (try running Haiku in Japanese, without
switching to VL-Gothic, you will see how digits are rendered with DejaVu and
everything else with VL-Gothic).
Moreover, by switching the fallback font from VL-Gothic to Noto Sans CJK JP
(JOP because historically this is where we have most CJK users - but feel free
to prove me wrong on that), we can get some of this working at least for our
Japanese users by default. Not as good as going with FontConfig, but it's an
easy change.
As far as I understand for better font rendering we need a modern font and
then improve our font
rendering. Much better commit messages than 'we just chatted a bit' please
for any commits like
this...
DejaVu *is* a modern font, it's still under active development and looks
great on, say, Ubuntu's
font rendering. We just need to improve our font rendering by using freetype
differently, although
the tweaks I made to app_server already helped significantly.
Also, I elaborated quite a lot in the commit message about why Noto isn't
actually better than
DejaVu. What should I have included?
There was already a discussion on the dev ML and the agreement was on switching
to Noto. If you want to switch back, the proper way would be:
1) Start a new discussion, bringing new facts such as:
- Users don't like it
- It doesn't work as expected
- DejaVu looks was improved in the meantime
And only then,
2) If people agree with the new arguments, switch back to DejaVu
My vote still goes +1 to Noto for the reasons explained in the first part of
this message, and because it provides a simple way forward when we get
fontconfig: it is much easier and nice-looking to switch between different Noto
variants, than to switch between an assortment of random fonts, for which we
must research language coverage, licensing, completeness, and looks.
