This issue is a little tricky. We are using Unicode fonts, unfortunately there
is no single font which covers the whole unicode range. Therefore PDFs are
currently rendered using up to 19 different fonts. In the case of vietnamese
the result is not perfect: Many glyphs can be rendered with the regular font
for the latin alphabet (DejaVuSerif), but quite a few glyphs are missing in
that font. Therefore the writer switches to DejaVuSans which has these glyphs. 

Possible solutions:

 * Switch to a different main font which has a better glyph coverage.
Prerequisite for that is a "font family" with a serif, sans serif and monospace
font. Each of these fonts needs a better glyph coverage as the currently used
DejaVu fonts.
 * Select different main fonts depending on the language of the wiki article.
This has the consequence that a PDF containing articles from multiple wikis
would have different main fonts. If e.g. vietnamese and english articles would
be mixed, this might look rather odd.
 * ...

Any thoughts on that anyone?

Until there is no solution that really improves the current situation I would
like to keep things as they are. I think, PDFs from the vietnamese wiki are
still usable even though the font switches are not ideal and look a litte odd.
