SVG fonts not being respected in PDF

[balmy geode]

Loading an SVG image with text disregards the fonts specified in the SVG and instead writes all text with the document's font.

Here's the SVG in question

Expected (as seen in Firefox or the system's image viewer) :

Especially, the monospaced text is lost

Was this created in the web app?

Probably means the font is somehow not available

Locally in vscode

Generated by PlantUML

The SVG specifies monospaceas the font, which should default to the defaut system monospace font

I guess changing it to a font that's actually installed on the system would work

Correctly rendered in Inkscape, the text box's font is, as suspected, the default monospace

Yeah, overwriting the font with a "real" font does works

Solved as follows :

let file = read("../figures/" + match.captures.first() +".svg")
if file != none {
    // set text(font: "Arial")
    file = file.replace("monospace", "Consolas")
    file = file.replace("sans-serif", "Arial")
    image.decode(file, width: width, height: height, alt: alt)
} else {
    panic("[eki] PlantUML : Rendered diagram not found: '../figures/" + match.captures.first() +".svg' Run PlantUML over the source document first.")
}

To clarify, monospaceis a generic font family defined in the CSS specification, which also applies to SVG. It should fall back to a "default" monospace font installed on the system (I would assume the default font that rawuses)
https://www.w3.org/TR/SVG11/fonts.html#FontFaceElementFontFamilyAttribute
https://www.w3.org/TR/2008/REC-CSS2-20080411/fonts.html#generic-font-families

The SVG file can be preprocessed as I've done above, so at least there's a way around the issue

👍 yeah it's possible that there are font fallback issues, but it's unfortunately not my "area of expertise" so I can't help much there. Feel free to open an issue about it in GitHub though.

[mystic kiln]

looks like one more case of typst not supporting generic families nor fontconfig

[balmy geode]

yeah this

it's a fallback issue
