It's not entirely clear to me either. The magnification of all dimensions used in the document was implemented in the classical TeX as a constant (so called MAG value) saved...

Sorry, I don't know, where the problem is. In LuaLaTeX or in the math font. If you try lualatex with `\usepackage{unicode-math}` and `$T$'` then you get the same bad result.

Your first problem was that luaTeX doesn't add italic correction at the end of the math list when Unicode math is used. With classical math, the italic correction is added....

You can experiment with the following code, which adds the italic correction at the end of the inline math mode. But I don't understand why this is not default behavior....

I mean that `\def\markdownRendererHeadingTwoPrototype#1{\chap #1^^M}` will not work because `^^M` is TeX-unfriendly character. OpTeX scans the line after \chap, \sec etc to its end in verbatim mode, i.e things like...

I tried to \input markdown in OpTeX but there are problems. It does \input expl3-generic and this macro file cannot be loaded in OpTeX without additional tricks. I hope that...

It is amazing! If there is a list of all control sequences generated by the convert Lua function (like `\markdownRendererEmphasis` in your example) and they are documented ,then I can...

I tried first attempt to set OpTeX macros with markdown package. But I don't understand many things, the `% ??` is here. For example, why there is `UlBeginTight `, `UlEndTight`....

Please, give me a source of this issue for experimenting with it.

I see that `\pagerightoffset`, `\pageleftoffset`, `\pagetopoffset` and `\pagebottomtoffset` are mentioned in LuaTeX manual but they are not documented here. Simply: don't use them. I don't see any reason to add...
