Well, the config file I attached in comment #12 does not make a
difference with an English locale, but it ought to change the behaviour
if LANG is zh_CN.UTF-8.

This indicates that the problem with fontconfig configuration and qt
apps is worse in the phone than elsewhere. So, before a change is made
to the seed, could you please test if the fonts-wqy-microhei package
gives the desired rendering?

I'm not sure I follow that: the LANG variable should change (as the
LC_MESSAGES) should, otherwise you wouldn't be able to switch languages.
Same for the LANGUAGE env var.

Could you be a bit more specific on which environment variable you don't
see changing? What's the output of the 'locale' command from the terminal
app?

Thanks!

 Title:
   Chinese in Ubuntu Touch should use Heiti style sans serif font

 Status in “ubuntu-touch-meta” package in Ubuntu:
   Triaged

 Bug description:
   Ubuntu Touch uses Kaiti style font as the main UI font for displaying
   Chinese, which is not optimal as nowadays operating systems all use
   Heiti style font for the UI, we should really change it asap.

   Currently there are two choices on Ubuntu, fonts-droid and wqy-
   microhei. Below I will list out the pros and cons.

   wqy-microhei (DroidSansFallbackFull.ttf, modified):
   - Pros:
 - The advantage of wqy-microhei being its wider codepoint coverage,
 for example it also contains Japanese Kanas and Korean Hanguls in one font.
 The downside is it may be of lower quality than the original
 DroidSansFallbackFull.ttf due to its lack of maintenance in recent years.
   - Cons:
 - I am not too much in favour of using wqy-microhei, the reason being
 that it is basically a font that based on the Droid font
 (DroidSansFallbackFull.ttf to be exact).
 - Upstream has not updated wqy-microhei for long time, so it lacks any
 new updates from the Droid font, although it may not be obvious to users.
 - Another possible disadvantage of wqy-microhei is it includes more
 latin characters, which may result to inconsistent glyphs being used.

   fonts-droid (DroidSansFallbackFull.ttf, original):
   - Pros:
 - The advantage is it has coverage of CJK ext. A [1], which
 wqy-microhei does not provide.
   -Cons:
- On the other hand, wqy-microhei has added some glyphs that the droid
 font does not provide, I don't have the exact number of that but I believe
 it's just a small number.
- The disadvantage is it does not include Korean Hangul, which can be
 remedied with another Korean font, and it's not our current concern anyway.

   As an additional alternative, just a few days ago, Google released the
   Noto Sans CJK fonts [2][3]:

   fonts-noto (Noto Sans CJK fonts):
   - Pros:
 - It takes care of different writing standards of Traditional Chinese,
 Simplified Chinese, Japanese and Korean, which makes everyone happy (see
 slide 13-14 of [3])
 - It covers Japanese and Korean as well
   - Cons:
 - Needs to be tested
 - Bigger size than the other alternatives as a result of catering for
 both Traditional and Simplified Chinese
 - Not yet packaged [4]

Well, that's confusing. I agree with David; we must be talking at cross-
purposes somehow.

Ok. Just made a merge proposal.

Regarding the license, there are two types of pacakges

1. fonts-android[1] included the binary fonts, which is licensed under 
Apache-2.0.
2. fonts-source-sans-pro[2]/fonts-source-code-pro[3], which required 
proprietary Adobe ADFKO to be built from source. That makes not DFSG-compatible.

Google Noto fonts[4] is same with Adobe Source hans sans[5], it depends how 
Debian/Ubuntu pack the font as debian packages. 
If the package need to be built from source, then it need Adobe ADFKO, which 
make it not DFSG-compatible

I'm also a little surprised.

Bug #1334495 is about qt apps and fonts-droid on a Kubuntu desktop.
However, the reporter of that bug confirmed in comment #13 that the
issue is not present in case of a Chinese locale.

Qt does not support fontconfig configuration well, the workaround is
to specify CJK font as the first candidate font instead of western font.

On the issue of DFSG-ness, it's still discussion only and no bug
tracking it.

I would advise to use wqy-microhei for the moment to RTM because such
bug isn't likely to have a proper fix land in a time. Though I didn't
see the issue with KDE environment, I didn't spend time on investigating
it either.

2014-07-28 Thread Gunnar Hjalmarsson
The attached fontconfig recipe might make it possible to still use
fonts-droid in the phone. It moves DroidSansFallbackFull.ttf to the top
of the candidate list in case of a Chinese locale, thus not affecting
non-Chinese languages.

On the desktop this is accomplished through the 69-language-selector-
zh-??.conf files in language-selector-common, but if I understand it
correctly, language-selector-common isn't included in Ubuntu Touch.

Aron, what do you say? Worth a try?

[Bug 1346766] Re: Chinese in Ubuntu Touch should use Heiti style sans serif font

2014-07-27 Thread Anthony Wong
** Description changed:

  Ubuntu Touch uses Kaiti style font as the main UI font for displaying
  Chinese, which is not optimal as nowadays operating systems all use
  Heiti style font for the UI, we should really change it asap.
  
  Currently there are two choices on Ubuntu, fonts-droid and wqy-microhei.
  Below I will list out the pros and cons.
  
  wqy-microhei (DroidSansFallbackFull.ttf, modified):
  - Pros:
    - The advantage of wqy-microhei being its wider codepoint coverage, for 
example it also contains Japanese Kanas and Korean Hanguls in one font. The 
downside is it may be of lower quality than the original 
DroidSansFallbackFull.ttf due to its lack of maintenance in recent years.
  - Cons:
    - I am not too much in favour of using wqy-microhei, the reason being that 
it is basically a font that based on the Droid font (DroidSansFallbackFull.ttf 
to be exact).
    - Upstream has not updated wqy-microhei for long time, so it lacks any new 
updates from the Droid font, although it may not be obvious to users.
    - Another possible disadvantage of wqy-microhei is it includes more latin 
characters, which may result to inconsistent glyphs being used.
  
  fonts-droid (DroidSansFallbackFull.ttf, original):
  - Pros:
    - The advantage is it has coverage of CJK ext. A [1], which wqy-microhei 
does not provide.
  -Cons:
   - On the other hand, wqy-microhei has added some glyphs that the droid font 
does not provide, I don't have the exact number of that but I believe it's just 
a small number.
   - The disadvantage is it does not include Korean Hangul, which can be 
remedied with another Korean font, and it's not our current concern anyway.
  
  As an additional alternative, just a few days ago, Google released the
  Noto Sans CJK fonts [2][3]:
  
  fonts-noto (Noto Sans CJK fonts):
  - Pros:
-   - It takes care of different writing standard of Traditional and Simplified 
Chinese
+   - It takes care of different writing standards of Traditional Chinese, 
Simplified Chinese, Japanese and Korean, which makes everyone happy (see slide 
13-14 of [3])
    - It covers Japanese and Korean as well
  - Cons:
    - Needs to be tested
    - Bigger size than the other alternatives as a result of catering for both 
Traditional and Simplified Chinese
    - Not yet packaged [4]

2014-07-26 Thread Cheng-Chia Tseng
I support Noto Sans CJK or Source Han Sans (they share the same content
of CJK part, while Adobe holds the copyright, licensed under Apache v2)
regular style for default CJK displaying.

That is absolutely better than Droid Sans Fallback because it takes care
of various region-specif shapes well and fits CJK characters displaying
better.

2014-07-26 Thread Gunnar Hjalmarsson
The Chinese font package currently seeded in Ubuntu Touch is fonts-
arphic-ukai.

On the desktop, fonts-droid is now the default Chinese font package as a
result of bug #1173571, and if we want this to be changed soon, I can
think it would make sense to replace fonts-arphic-ukai with fonts-droid
in the touch seed.

As regards Noto, the new CJK fonts are not yet included in the fonts-
noto package. There is a Debian bug about it:
https://bugs.debian.org/754926

** Bug watch added: Debian Bug tracker #754926
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754926

2014-07-26 Thread Aron Xu
At this very moment, Source Sans is still not an option and there are
also questions to be answered to determine whether it fits the
requirement of DFSG.

Comparing wqy-microhei and fonts-droid, there is no reason to continue
using microhei anymore, because after several updates of Droid Sans, the
coverage problem is already improved (and wqy-microhei stops its
development right after this is the fact) to be wider than wqy-microhei.
