My understanding (reading https://developer.mozilla.org/en-US/docs/Web/CSS/font-family) is that only the family name should be quoted if it contains spaces.\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib\r\nimport matplotlib.pyplot\r\nmatplotlib.rcParams[\"svg.fonttype\"] = \"none\"\r\nmatplotlib.rcParams[\"font.family\"] = \"sans-serif\"\r\nmatplotlib.use(\"SVG\")\r\n \r\nfig = matplotlib.pyplot.figure()\r\naxes = fig.add_subplot()\r\naxes.plot([1, 2], [3, 4], label=\"test\")\r\naxes.legend()\r\nfig.savefig(f\"test.svg\")\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\nIn the text elements, the generic name of the font-family is quoted (here 'sans-serif')\r\n`\u003ctext style=\"font: 10px 'sans-serif'; text-anchor: start\" x=\"94.6\" y=\"57.629812\" transform=\"rotate(-0, 94.6, 57.629812)\"\u003etest\u003c/text\u003e`\r\n\r\n### Expected outcome\r\n\r\nThe generic name of the font-family should not be quoted\r\n`\u003ctext style=\"font: 10px sans-serif; text-anchor: start\" x=\"94.6\" y=\"57.629812\" transform=\"rotate(-0, 94.6, 57.629812)\"\u003etest\u003c/text\u003e`\r\n \r\n\r\n### Additional information\r\n\r\n_No response_\r\n\r\n### Operating system\r\n\r\n_No response_\r\n\r\n### Matplotlib Version\r\n\r\n3.5.1\r\n\r\n### Matplotlib Backend\r\n\r\nSVG\r\n\r\n### Python version\r\n\r\n3.9.10\r\n\r\n### Jupyter version\r\n\r\n_No response_\r\n\r\n### Installation\r\n\r\nconda","author":{"url":"https://github.com/cderemble","@type":"Person","name":"cderemble"},"datePublished":"2022-02-22T09:10:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/22528/matplotlib/issues/22528"}
