How to escape backticks (any string) to write latex code inside minted block in (lua)latex?

Question

I have seen similar questions (a, b, c) but this one is a bit different.

Yesterday I was so excited to start learning latex and quick enough I discovered packages that can render any source code. But in my program, there are some Unicode (multibyte) characters that are not rendered with standard font families. So I used emoji package for this. And soon after that I couldn't render these special characters inside (TypeScript) string which is inside minted block.

Surely I can escape by using the same type of quotes around the latex code inside string: "string "|\escaped|" string", but this will render another pair of quotes in PDF, so this won't work.

AFAIK, I should use another package, but minted is soo good. How can I solve the problem without ditching minted package?

Here is a short example:

\documentclass[a4paper]{article}
\usepackage[cachedir=../.cache, outputdir=output]{minted}
\usepackage{emoji}
\def\done{\emoji{check-mark-button}}
\begin{document}
\noindent It shows here (outside minted) -> \done
\begin{minted}[escapeinside=||]{typescript}
...
hbs.registerHelper("list", function(this: any) {
  ...
  entries.forEach(entry => {
    |It shows here (inside minted) -> \done|
    rows += |But not in here (inside minted and backticks) -&gt; \done| ...
  })
  ...
});
...
\end{minted}
\end{document}

And the output:

Same cause as italic - Minted escapeinside doesn't work within a string - TeX - LaTeX Stack Exchange but I don't know how generalizable is the answer because I didn't look at the manual to see what \PYG does — user202729, Oct 06 '22 at 12:01
@user202729, yes. But in my case, I have a lot of characters on multiple lines between quotes (backticks) and escapeinside=|| doesn't seem to work when escape characters (start | and end |) are placed on different lines. — Andrew15_5, Oct 06 '22 at 14:25
escapeinside comments and strings is a GitHub issue, according to the documentation. — Cicada, Oct 07 '22 at 09:46
@Cicada, can you provide a link to the issue? I can't find it (or the issue covers a slightly different problem). — Andrew15_5, Oct 07 '22 at 13:55
Might be unrelated, but for reference: "'fancyvrb’ print[s] a line only after finding it[s] end character" (fancyvrb-doc.pdf, p6), that is, a comment character hides the line-end character. Note also that fvextra package does some patching - I don't know if it affects multilines, but probably not since the closing back tick (and colour) is applied to the first line only. — Cicada, Oct 07 '22 at 14:20

Not sure what you're after, but how about this?

An indirect (=meta) command for the backtick (grave accent), option1; or mixing in some Pygment metacommands, option2.

In both cases, the special character is "hidden" from the lexer, and is inserted "manually", so to speak.

Fonts and red colour arbitrarily chosen for demonstration purposes for 1 and 2. Option 3 is the minted colour scheme.

MWE

\documentclass{article}
\usepackage{minted}
\usepackage{fontspec}
\newfontface\fsym{Noto Sans Symbols2}
\newfontface\fsymb{Noto Emoji}
\def\done{{\fsym ☑✓✔}{\fsymb ✅}}

\newcommand{\metastringb}[1]{\PYG{l+s}{\Uchar96}\PYG{l+s}{#1}\PYG{l+s}{\Uchar96}}

  ...
  entries.forEach(entry => {
    |It shows here (inside minted) -> \done|
    rows += |\Uchar96|
    |{\color{red}1. But not in here (inside minted and backticks) -> \done}|
    |\Uchar96|
        ...
|\metastring{2. But not in here (inside minted and backticks) -&gt; \done}|

|\metastringb{3. But not in here (inside minted and backticks) -&gt; \done}|


})
  ...
});
...
\end{minted}
\end{document}

The big problem that I encountered, after trying using several methods (and including this one), is that the coloring is not applied to things such as \${this}`` (putting variables inside interpolated string). — Andrew15_5, Oct 07 '22 at 13:46
