Additional comments
I can reproduce this issue, can't seem to figure out what's causing it though. I tried putting the text in a \foreignlanguage{russian} as described here and that made it write to TeX fine and generate the SVG as well. But for some reason the only character displayed is the exclamation mark. I tried checking the DVI file being produced and MiKTeX's DVI viewer couldn't open it saying something like Some PostScript specials could not be rendered. which might be a cause for it since it would run into problems later with dvisvgm later.
Requires more investigation, if anyone is willing to take this up.
