描述

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.

研究方向
Investigate how Idyll processes math equations, specifically the parsing of LaTeX like syntax. Compare with KaTeX behavior to identify where the strictness issue arises. Look at the math rendering module in the Idyll source code (likely under packages/idyll ast or similar) to find where the error is thrown for non standard symbols like ⨾. Consider adding an option to configure strictness or handle such symbols gracefully.
