Rendering Chinese characters problem Question Mark

#27149

Hi,

We are currently using Arialuni.ttf for rendering chinese characters however from time to time we are getting rendering issues for the chinese and is defaulting to (?) question mark.

I suspect that as the Arialuni.ttf is 20MB it is taking some overhead on the rendering and causing failures.

is there a way to optimize this approach?

here is our properties file which we use to embed the TTF:
Arial=arialuni.ttf
Serif=arialuni.ttf
Times New Roman=arialuni.ttf
SimSun=arialuni.ttf

Any advise would be much appreciated

Take a look to the TTF fallback tables on the page:

In principle you may use the font names (ignoring their original meanings) to define a chain of CJK TTF fonts, to be used to find a particular glyph, missing in the main font:

[language=java:1nn401ks]MS Gothic=cjk_font_option1.ttf
MingLiU=cjk_font_option2.ttf
SimSun=cjk_font_option3.ttf
Mangal=cjk_font_option4.ttf
David=cjk_font_option5.ttf
Gulim=cjk_font_option6.ttf  [/language:1nn401ks]
