Comment 13 for bug 1334495

I tried both.
If I change the locale in my existing installation to simplified Chinese, all Chinese text is displayed correctly. (fonts-droid installed and language-selector-common updated to the Utopic version.)

I also installed Kubuntu 14.04 with German locale in a virtual machine and applied all updates. In the fresh installation the problem is slightly different: In Chinese text, some characters are not displayed at all, instead the standard squares that are used when a font doesn't include the required characters are displayed.
