The code path was also not working at all on Py3 (#10046).\r\n\r\nI would thus suggest deprecating support for svg fonts.\r\n\r\nA possibility to still allow embedding the font file into the svg file would be to use the apparently more popular WOFF(2) format, see https://developer.mozilla.org/en-US/docs/Web/Guide/WOFF https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face for the format, http://www.sameratiani.com/2011/10/16/embed-inline-webfonts-in-css.html for embedding the font into the svg file itself, and https://caniuse.com/#search=woff for support.  A quick test suggests that this is supported but chrome/firefox, but not by inkscape, but at least inkscape emits a warning and replaces the embedded font by another one, whereas it appears to freeze with the current implementation of svg fonts.","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2017-12-20T19:06:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/10063/matplotlib/issues/10063"}
