Support multiple fonts in math by mkorje · Pull Request #6365 · typst/typst

Font handling

The default math font (new computer modern math) has been added to the text font fallback list. This means that math will always be able to render, as long as the user doesn't #set text(fallback: false).

The way in which font fallback in math works is nearly identical to normal text layout. The key difference is that we only use fonts that have a MATH table present, skipping ones that don't. Note that while strings in math don't use the text font, they do go through normal text layout. So $🍏$ will render as a tofu, whereas $"🍏"$ will not.

Math layout will fallback through all available fonts, and has its own set of fallback fonts distinct from normal text.

Test changes caused by font handling

math-font-fallback: Font fall back in math only goes through fonts with a MATH table.

Old	New

--- math-font-fallback ---
// Test font fallback.
$ よ and "よ" and 🏳️‍🌈 $

math-lr-scripts: The zws is now just ignored, so it no longer removes the spacing after the lr. (i.e. the test now matches what it would look like if the zws weren't there.)

Old	New

--- math-lr-scripts ---
// Test interactions with script attachments.
$ lr(size: #3em, |)_a^b lr(size: #3em, zws|)_a^b
  lr(size: #3em, [x])_0^1 [x]_0^1
  lr(size: #1em, lr(size: #10em, [x]))_0^1 $

Repr in math

RawElem in math is kinda weird. At the moment it basically ends up going through layout_external since the font has changed:

typst/crates/typst-layout/src/math/mod.rs

Lines 474 to 481 in 0a3c693

    
           // Hack because the font is fixed in math. 
        
           if styles != outer 
        
               && styles.get_ref(TextElem::font) != outer.get_ref(TextElem::font) 
        
           { 
        
               let frame = layout_external(elem, self, styles)?; 
        
               self.push(FrameFragment::new(styles, frame).with_spaced(true)); 
        
               continue; 
        
           }

To preserve this behaviour, I've opted to cut any processing of RawElem off during realisation in math mode and add a check to not set the baseline for a RawElem.

Multiple fonts in math

As the name of the PR would suggest, multiple fonts now just work in math. No need for box hacks anymore.

New tests as examples

math-font-features-switch: You can use glyphs from a font's stylistic sets now. Notice that the math kerning with the subscripts is still working!

--- math-font-features-switch ---
#let scr(it) = text(features: ("ss01",), $cal(it)$)
$cal(P)_i != scr(P)_i$, $cal(bold(I))_l != bold(scr(I))_l$
$ product.co_(B in scr(B))^(B in scr(bold(B))) cal(B)(X) $

math-font-covers: You can use covers with fonts in math now, so that specific glyphs are from a given font. Again, notice the kerning with the subscripts.

--- math-font-covers ---
#show math.equation: set text(
  font: (
    // Ignore that this regex actually misses some of the script glyphs...
    (name: "XITS Math", covers: regex("[\u{1D49C}-\u{1D503}]")),
  ),
  features: ("ss01",),
)
$ cal(P)_i (X) * cal(C)_1 $

math-op-font: You can use any font you'd like operators and limits will work as specified.

--- math-op-font ---
// Test with different font.
#let colim = math.op(
  text(font: "IBM Plex Sans", weight: "regular", size: 0.8em)[colim],
  limits: true,
)
$ colim_(x -> 0) inline(colim_(x -> 0)) $

math-op-set-font: Notice the improved kerning between the letters in each operator (less space between c and h in sech, more space between o and d in mod) as well as the ligature.

--- math-op-set-font ---
// Test setting font.
#show math.equation: set text(weight: "regular")
#let lig = math.op("fi")
#let test = $sech(x) mod_(x -> oo) lig_1(X)$
#test
#show math.op: set text(font: "New Computer Modern")
#test

More customisation and control

Whenever a glyph is laid out in math by Typst (e.g. the delims for matrices, the accent glyph for accents), it now goes through realisation. Essentially, this means you can now target them with show rules. Combine this with proper support for multiple fonts, and you can do all sorts of stuff (even very cursed things)!

New tests as examples

math-root-show-rule-1

#show "√": "!"
$ sqrt(2) root(2, 2) $

Why is raw emoji showing but #emoji is not?

Why is raw emoji showing but #emoji is not?

I don't know exactly what you're referring to, but it probably has to do with math fonts not having emojis in them.

istudyatuni · 2025-06-03T07:20:05Z

When written as $🍏$ , emoji is rendered, but when as $#emoji.apple$ , is not

Yes, that's why.

When written as $🍏$ , emoji is rendered, but when as $#emoji.apple$ , is not

I can't reproduce this, they both render as tofus on this branch.

This error is new, right? I guess relying purely on fallback does not work with the font stack thing, but also generally fails because we need all those metrics?

This seem a bit inconsistent with how font fallback otherwise works in Typst, but I guess it is not more restrictive than before with "current font is not suitable for math".

It's basically replaced the old "current font doesn't support math" error thing. Yeah, we just need to grab whatever the current font is for the metrics.

Surely though this error will basically never occur, right? (Unless the font specified doesn't exist and fallback is disabled, I guess)
