[Bug 1475205] Re: Random Chinese character missing with Ubuntu font
Basically, this patch fixes both. The main reason why it *only* fixes PC, but not for touch is that we forget to re-compile qtubuntu(libqpa-ubuntumirclient.so) to make this work.Compiling qtbase automatically enable qpa(linuxfb,eglfs...) linked against patch applied qtbase module. So we can't reproduce this issue on PC(linuxfb). However as a standalone qpa plugin,ubuntumirclient is not native supported,which means it's not in qtbase/src/plugins/platforms).So ubuntumirclient can't find the new added symbol(QFontconfigDatabase::fontsAlwaysScalable()).And it didn't work out on touch. Please check the attached picture. I test and verify my patch on bq. ** Attachment added: "fix-on-touch.png" https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1475205/+attachment/521/+files/fix-on-touch.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475205 Title: Random Chinese character missing with Ubuntu font To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1475205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1475205] Re: Random Chinese character missing with Ubuntu font
Copy bug description https://bugreports.qt.io/browse/QTBUG-47547 and
paste here.
if developer specifies font family with Non-Regular style, potential risk to
encounter Chinese characters are missing in some cases .
E.g
import QtQuick 2.4
import QtQuick.Controls 1.3
ApplicationWindow {
visible: true
width: 1280
height: 800
Text {
anchors.centerIn: parent
text: "系统设置"
font.family: "Ubuntu"
font.pixelSize: 69;
font.weight: Font.Light
}
}
Regarding the code snippets above.
For Chinese characters, QFontDatabase will use fallback font family("Droid Sans
Fallback") with "Light" style when add font Glyph.
since QFontDatabase checks if default style(Regular) of fallback font family
"Droid Sans Fallback" is same as font style specified in qml(Font.Light). And
QFontDatabase::isSmoothlyScalable will return false in such a case, which
results in scene graph will
use QSGDefaultGlyphNode when createGlyphNode is called. Issue happens.
However If scene graph doesn't prefer NativeGlyphNode and create GlyphNode
based on Distance Field technique. It works fine.
https://drive.google.com/open?id=0B2H9ECPSSfqIMzhvU1hPUWNlWnc
Need to only check styleKey when foundry->styles == specified style
Will see feedback from Qt guys.
Thanks.
PS: more test cases and patch can be found on
https://bugreports.qt.io/browse/QTBUG-47547
Also I think we can override bool QBasicFontDatabase::fontsAlwaysScalable()
method in qlinuxfbfontdatabase.cpp under qtbase/src/plugins/platforms/ for
platform independent purpose.

[Bug 1475205] Re: Random Chinese character missing with Ubuntu font
FWIW this shows missing characters as well, very few fonts have a Light
version.
Text {
text: "系统设置 Bookman Light 69px"
font.family: "URW Bookman L"
font.pixelSize: 69
font.weight: Font.Light
}

[Bug 1475205] Re: Random Chinese character missing with Ubuntu font
Does this happen with other strings in Chinese as well? Can you give a few more examples? Or is it specific to these 4 characters? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475205 Title: Random Chinese character missing with Ubuntu font To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1475205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1475205] Re: Random Chinese character missing with Ubuntu font
So it only happens if all conditions are met: Font is Ubuntu and Qt falls back to Droid Sans Fallback (which is from package fonts-wqy-microhei) Pixelsize is 69 as computed from the 50GUs and Grid Unit size of 23 Font weight is Light Random characters are not shown. Seems a bug in Qt's font fallback logic - similar report at https://bugreports.qt.io/browse/QTBUG-32470 Can someone try on Wily? ** Attachment added: "Main.qml" https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1475205/+attachment/4432959/+files/Main.qml ** Also affects: qtdeclarative-opensource-src (Ubuntu) Importance: Undecided Status: New ** Changed in: ubuntu-font-family-sources (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475205 Title: Random Chinese character missing with Ubuntu font To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1475205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm this happens on font.family: "Ubuntu", the default fallback font of Chinese seems to be "Droid Sans".
