How to set an exact line height no matter which font is used in the line?

I am a multilingual user, English and Chinese at the same time. Currently I need four different fonts and I set them up like this:

//default fonts & text settings
#let ENsans = "Helvetica Neue"
#let ENserif = "Charter"
#let Hei = "Heiti SC"
#let Song = "Songti SC"

//font Groups
#let sans = (ENsans, Hei)
#let serif = (ENserif, Song)
#set text(
  font: serif,
  size: 12pt,
  weight: "regular",
)

The problem is that in cases where I need two fonts in a line (Charter for English & Songti for Chinese), the default line height is the determined by the highest font in the line, which make the paragraphy line distributed unevenly. An example of the problem can be seen in the picture below.

The lines with English words like “LaTeX”, “Markdown” are noticably higher, even when they are in the same paragraph.

I have tried #set par(leading: 0.65em), but this only affects the spacing between lines instead of the exact height of the line. How can I force the height of lines to be the same? And if it is not possible, 使用中文的同志们有没有样式比较正常的同时支持中英文的字体推荐呢？

You need set text(top-edge: 1em) or something similar. The default is cap-height, which is font-dependent.

Great Thanks! This does solve the problem!! The lines are now distributing evenly!

However another problem occurring is that, the baseline of English words are a little bit too high up, compare to that of Chinese characters, can I adjust another parameter to make the baseline higher?

I also did this experiment:

rect(fill: aqua)[

As you can see,

the baseline is a bit low in the line.

There is a baseline parameter, but I’ve never used it.

I’ve tried show text.where(font: "xxx"): show text(baseline: xxem) to set specific baseline for Chinese fonts. But this doesn’t work :smiling_face_with_tear:

Maybe you’re not using the right font name in the show rule… After you do set text(font: ...), try something like context panic(text.font) to see what name is actually used by Typst.

Still no good. But thanks for the advice. I’ll try a different font instead.

It seems that the show text.where(font: "xxx"): set text(...) method works only when text.font is set to a single value… So this works:

#show text.where(font: "noto sans tc"): set text(baseline: -0.3em)
#lorem(5)
#set text(font: "Noto Sans TC")
天地玄黄 宇宙洪荒 日月盈昃 辰宿列张 寒来暑往 秋收冬藏

but this doesn’t work:

#set text(font: (
  (name: "Noto Sans TC", covers: regex("[\p{Han}]")),
  "Libertinus Serif",
))
#show text.where(font: "noto sans tc"): set text(baseline: -0.3em)
#lorem(5)
天地玄黄 宇宙洪荒 日月盈昃 辰宿列张 寒来暑往 秋收冬藏

A more robust and cleaner way to do this could be with functions to set the font explicitly for each piece of text:

#let latin = text.with(font: "Libertinus Sans")
#let chinese = text.with(font: "Noto Sans TC", baseline: -0.3em)

#latin[#lorem(5)]
#chinese[天地玄黄 宇宙洪荒 日月盈昃 辰宿列张 寒来暑往 秋收冬藏]
