Font: should not fallback for the whole text

[bczhc]

There's a very simplified svg:

<svg xmlns="http://www.w3.org/2000/svg" width="100mm" height="30mm" viewBox="0 0 100 30">
<text x="28.026342" y="12.053369" font-family="DejaVu Serif" font-size="4.23333">Deja Vu Serif/中文</text>
</svg>

Now on my system there's DejaVu Serif installed, and you can see obviously this font won't contain Chinese characters. So here, when I run svg2pdf it will report Warning (in usvg::text:183): Fallback from DejaVu Serif to FZKai-Z03., Later, open the produced PDF, a font fallback on this whole line was observed:

Expected result (English keeps DejaVu Serif and Chinese fallbacks to Noto CJK:

rsvg-convert and inkscape, or directly opening the svg with browsers, do this well, so I suppose this is an svg2pdf bug.

Version: svg2pdf-cli 0.13.0

I noticed #65, just not seeing the same issue got filed. Feel free to close this in favor of that.

p.s. From my experience with this project, I found svg2pdf works much much better with clipping/masking than inkscape and rsvg-convert!!

Thanks for the report. I suspect this is a bug in usvg itself, because svg2pdf doesn't do any font resolving, this is all handled by he underlying library. Font fallback is unfortunately known to be rather weak in usvg.

Glad to hear that, I've definitely put a lot of effort into getting clipping and masking (as well as weird combinations of them) correct. :)
