I don't think this is correct, e.g.

rcParams["svg.fonttype"] = "none"; figtext(.5, .5, "hello", font="DejaVu Sans"); savefig("/tmp/test.svg")

results in

<text style="font: 10px 'DejaVu Sans', DejaVu Sans; text-anchor: start" x="230.4" y="172.8" transform="rotate(-0 230.4 172.8)">hello</text>

where the unquoted DejaVu Sans is likely wrong? (at least wrt. the spec)

@not-so-rabh could you comment on @anntzer's question?

Converted to draft - needs discussion and rebase

The issue that @anntzer points out is real, we need to only add the un-escaped font name if the name is one of the generic names.

There is also some confusion about what get_name and get_family on FontProperties do. get_family gives back the list of font names (which font tools call families) and get_name turns the crank on our font search code and return the family of the font actually found on the users system.

This line of code also was impacted by #23559 and the fix for #23492 will also touch this line. I think I see how to fix both #22528 and #23492 in one shot and in the interest of trying to squeeze these in for 3.6 am just going to do it.

Thank you for your work on this @not-so-rabh , I apologize for taking this issue from under you, and I hope we hear from you again!

Replaced by #23638
