Both the binary and modified demo source code are provided in the package:

Here are some screenshots:


When the program is loading and displaying texts with Chinese fonts,
we can experience slow speed and high memory usage as HyperIris stated in another forum post.
(http://www.cegui.org.uk/phpBB2/viewtopic.php?t=1771)
Moreover, I found when displaying with the KaiU font, the chinese words will brake apart.
(Shown as the following screenshot) This is also happening in some X-window misconfiguration.
I think the reason is the bytecode interpreter is disabled in the FreeType2 library.
Enabling it should solve this problem.

Hope this demo helps.
