Chinese and french characters in web pages

Dear Dillo developers,

First of all, I want to thank you for the great web browser dillo is:
it is very fast, has most of the features I want and the rendering is
improving greatly (I am using hg version currently).

I would like to use dillo to view web pages written in chinese and
also pages written in french. Currently, I cannot do both.  To view
web pages in chinese, I set the following fonts in my .dillo/dillorc:

    font_serif="WenQuanYi Bitmap Song"
    font_sans_serif="WenQuanYi Bitmap Song"

The problem is that french characters like à, é or è are not displayed
with this font.

To view web pages in french, I set the following fonts:

    font_serif="DejaVu Serif"
    font_sans_serif="DejaVu Sans"

But then, chinese characters are displayed as empty squares.

Is there a way to read both languages in the same instance of dillo?

Thanks,

Christophe
