From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[The author assumes] a high-level understanding of how text rendering works, for example, what shaping is. If that does not sound familiar to you, you might want to review State of Text Rendering (2009), and Modern text rendering with Linux: Overview (2019).

Fonts have been programs for a long time. Better to have the code in a safe VM than natively executed.

Do you have a link for that, or a term I can search for? I'm not finding anything about it.

Here are a couple of links that should be good starting points:

https://superuser.com/questions/1202551/can-truetype-fonts-contain-malicious-code

https://security.stackexchange.com/questions/91347/how-can-a-font-be-used-for-privilege-escalation

That is interesting. WASM seems like it's just a replacement for the TrueType hinting language (which is already a VM). So I guess it's benefiting from a more standardised and audited virtual machine.

It's also fairly limited to what it can do (source):

you can influence the process of mapping a string of characters into an array of glyphs, you can determine how those glyphs are positioned and their advance widths, but you cannot manipulate outlines, variations, line breaks, or affect text layout between texts of different font, variation, language, script or OpenType feature selection

I don't see how the mentioned future drawing API will fit into that though.

Yeah, the real benefit will be the ability to re-use well tested and hopefully even proven WASM VMs.
