Description

Math tags shows Cyrillic text and other characters in thin, angular font. At the same time, many Latin characters, and even Chinese and Arabic, appear in a thick, smooth, pretty font.

In Wikipedia with Cyrillic, we use a lot of text in formulas and formulas are shown from two different fonts, not as pretty as in other languages.

It is necessary that more text is displayed in a pretty font.

As can be seen from the svg, the part in the path tag and part as text tag

  1. why server can't draw everything in path and give everyone the same picture
  2. text tag with font-family="monospace" so characters are displayed depending on browser and os. Firefox on win 10 gives Courier New for monospace when latin letters are drawn by path and serif. These two fonts look very different. Mobile opera mini for the Cyrillic shows tofu symbols, although it shows the Cyrillic text itself; and Latin characters in the path are of course visible
  3. why \text{} shown partially by text and partially by tag. It gives a mixture of monospace and serif inside one word and differences in the height of the letters <math>\text{Žemaitėška}</math>
  4. also an option add css class for text in the svg so that wikipedians can locally configure the class via css

I do not consider that thin (Firefox 64 on Linux):

I do not consider that less 'pretty':

As "pretty" is subjective, do you have specific fonts in mind which support cyrillic and look more similar to the non-cyrillic ones?

For Cyrillic letters in svg

font-family="monospace"

and depends on the browser and os.
Latin letters are drawn by path (and serif).
Bold and smooth vs thin and agular and second font - in firefox (default for cyrilic Courier New) win 10 the difference in many formulas is big and striking.

As "pretty" is subjective, do you have specific fonts in mind which support cyrillic and look more similar to the non-cyrillic ones?

Something similar to the font of Latin letters and plus they could have been drawn together in path. Or a set of fonts which is used in Wikipedia for articles text.

depends on the browser and os.

If this is known to you then please include such crucial information in the initial task description. Thanks!

  1. why server can't draw everything in path and give everyone the same picture

This is a general problem that relates to several other issues (cf. T50032) and comes down to font limitations.

The underlying problem is that MathJax (used by Mathoid / the Math Extension) is configured to use a font (derived from Computer Modern) which has fairly limited Unicode support. Switching to another supported font with wider Unicode support (e.g. STIX) is technically easy but will lead to visual changes (and won't cover e.g. Chinese characters either).

In the long run, MathJax might add support for a font like NOTO to provide very wide coverage but that's a way off.

  1. text tag with font-family="monospace" so characters are displayed depending on browser and os. Firefox on win 10 gives Courier New for monospace when latin letters are drawn by path and serif. These two fonts look very different.

That's MathJax fallback behavior when a codepoint is not covered by the font. Since e.g. Wikipedia does not set any font for the body text (just serif), it's not possible to choose a matching font.

As noted in other issues the quality would probably improve if SVGs were not loaded via img tags but inlined in the HTML.

Mobile opera mini for the Cyrillic shows tofu symbols, although it shows the Cyrillic text itself; and Latin characters in the path are of course visible

That sounds like a browser bug. Not sure that's in scope.

  1. why \text{} shown partially by text and partially by tag. It gives a mixture of monospace and serif inside one word and differences in the height of the letters <math>\text{Žemaitėška}</math>

That's because those characters covered by the font will be converted to SVG paths, those that need fallbacks will use SVG text elements.

  1. also an option add css class for text in the svg so that wikipedians can locally configure the class via css

That would be possible (in fact it's already simple to write a selector) but it has no effect since SVGs are loaded via img tags and CSS won't reach them (unless you add it to the SVG file which is not possible either and opens a whole different set of problems).

@Sunpriat May I ask you what exact OS you're on? In the Wikimedia Design team we've been working on finding better proposals for operating system/language font solutions that might enable better readability than the generic sans-serif, serif and monospace font family choices, see “Operating system default sans-serif font”.

what exact OS you're on?

win 10 1803 17134.472 (ru), Firefox 64.0 (ru)
For a math tag, there probably is an opportunity to add all unicode text drawing with this "better readability" font directly to the svg-path (OS-independently, before sending picture to the reader).
