[Bug 1334495] Re: Two different fonts mixed to display Chinese text in all desktop applications

[Lukas Bunsen]

I experimented a bit more yesterday. I didn't find a option for the sub-
locales in KDE, but installed language-selector-gnome, where it is
possible to change.

To be on the safe side, I just also directly edited /etc/default/locale
as suggested by you.

After reboot:

"cat /etc/default/locale
LANG="de_DE.UTF-8""

"locale
LANG=de_DE.UTF-8
LANGUAGE=de:en:zh:en
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY=de_DE.UTF-8
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_ALL="

The problem still exists.

Additionally I tried some more programmes. My impression now is that the
problem only exists with KDE, e.g. QT programmes and things like all
window titles. In Gnome applications (I tried Geany and Pidgin) Chinese
text is displayed normally, in Thunderbird too (not sure what toolkit
thunderbird uses).

I deinstalled "fonts-arphic-ukai" which seemed to be the "italic" font
used. Now, text is still displayed using two different fonts, but the
"italic" font changed. (I am using "italic" and "normal" to describe how
the fonts look, but it is not equal to a text's attribute in Latin
script. The difference between the two fonts could perhaps be compared
to serif and sans serif in Latin script)

In the font settings, everything is set to Ubuntu, except for the
monospace font which is set to Monospace.

Title:
  Two different fonts mixed to display Chinese text in all desktop
  applications

Status in “language-selector” package in Ubuntu:
  Incomplete

Bug description:
  Bug:
  In all desktop applications, two different fonts are mixed to display Chinese text. I attached a screenshot of a paragraph of Chinese text in Kmail - some characters are displayed using a "italic" font, others in a "normal" font. The same problem exists in other applications, for example Dolphin or even Konsole. In Xterm, only the "normal" characters are displayed, where Dolphin displays italic characters Xterm leaves a white space. Websites are displayed fine, if I open the same mail in the web interface only one font is used.

  Background

  I' am using Kubuntu 14.04 with the language set to German in KDE settings.
  The output of "locale" looks a bit messed up, I don't know why, as in the KDE settings all formats are consistently set to German standard. 
  "locale                                                                                                         
  LANG=de_DE.UTF-8
  LANGUAGE=de:en:zh:en
  LC_CTYPE="de_DE.UTF-8"
  LC_NUMERIC=zh_CN.UTF-8
  LC_TIME=zh_CN.UTF-8
  LC_COLLATE="de_DE.UTF-8"
  LC_MONETARY=zh_CN.UTF-8

  This is my first bug filed at launchpad. I filed it for language-selector as other related bugs I found were filed for the same package. If it isn't language-selector, perhaps you can point me to the right package?
