After exporting the file, the following manual adjustments had to be applied: explicitly specify width and height in the top-level <svg> tag; delete all occurrences of some mysterious &#xf39f; token; replace all occurrences of &#xf048;, &#xf04c;, and &#xf090; with symbols "(", ")", "/" respectively, and made them Arial.
