Description

Describe the bug

Idyll fails to render math formulae with ⨾ symbol.

To Reproduce Steps to reproduce the behavior:

  1. [Equation]f \mathbin⨾ g \in \operatorname{hom}(A, C)[/Equation]

Expected behavior

Idyll should show the formula correctly.

Desktop:

  • OS: NixOS
  • Browser: Firefox
  • Version: 84.0.2

Additional context

KaTeX actually shows this correctly: https://katex.org/?data=%7B%22displayMode%22%3Atrue%2C%22leqno%22%3Afalse%2C%22fleqn%22%3Afalse%2C%22throwOnError%22%3Atrue%2C%22errorColor%22%3A%22%23cc0000%22%2C%22strict%22%3A%22warn%22%2C%22output%22%3A%22htmlAndMathml%22%2C%22trust%22%3Afalse%2C%22macros%22%3A%7B%22%5C%5Cf%22%3A%22%231f(%232)%22%7D%2C%22code%22%3A%22f%20%5C%5Cmathbin%E2%A8%BE%20g%20%5C%5Cin%20%5C%5Coperatorname%7Bhom%7D(A%2C%20C)%22%7D. But it warns on a non-standard symbol, so if you enable strict mode, it throws an error. It seems like Idyll is overly strict on math, and there seems to be no option to make it less strict.

Contributor guide

Research direction
Examine how Idyll processes math expressions, specifically the handling of non standard Unicode characters like '⨾'. Check if there is a strict mode or escape mechanism that can be configured to allow such symbols.
