LaTeX (doc): explain how to allow Unicode input in math #5693
Conversation
There was a problem hiding this comment.
I did not test much HTML+MathJaX but it renders well α and 𝚹 and ∫ for example. Only way I know in LaTeX for same level of support is to use xelatex/lualatex with unicode-math. On the other hand it is debatable to add unicode-math to default xelatex/lualatex conf, as it adds overhead and slows down compilation significantly. And its usage may need some user customization such as math-style=literal which we can not guess.

I did not comment on Japanese case: α is ok but for example 𝚹 is not in my brief testing.

I think this isn't a bug fix. So I feel a bit strange for this entry.

of course, don't know why I added this entry. I will remove that. And I will try to make the added explanations a bit less verbose. (as matter of fact I find our LaTeX doc occupies already much space...)

merging, thanks for reviewing! (I refactored a bit after that, I hope all for the best :) ) |
Closes: #5249
This is only update to documentation.
There is no solution for pdflatex, and it appears unneeded to add per default
unicode-mathusage forxelatex/lualatex(especially as some option may be needed to pass to the package as explained in the added documentation from this PR).Thus I propose this as "fix" of #5249.
