Something strange with algorithm2e comment. I'd like to make the left marker of the comment be a long dash. Similar to \textemdash. I was following the answer given here how-to-have-the-algorithmicx-comment-symbol-in-algorithm2e but instead of using a triangle marker as in the above link, I wanted instead to use ---. But I can't get it to work. (Actually the example in the answer above, does not compile for me on TL 2016).
When I try \SetKwComment{comment}{\textemdash}{}, I do not get what I expected. I get something else. MWE
\documentclass{article}
\usepackage[linesnumbered]{algorithm2e}
%now set comment left marker
\SetKwComment{comment}{\textemdash}{}
\begin{document}
This \textemdash\ is a test.
\begin{algorithm}[H]
\DontPrintSemicolon
\SetAlgoLined
\eIf{true}
{
$x=1$ \comment*{Some comment}
}
{
$x=0$
}
\end{algorithm}
\end{document}

I am doing something wrong. How to obtain --- for left comment marker? If I just write \SetKwComment{comment}{---}{} I get this:
And they are not the same. I want the dash that looks solid, like on the first line above.
TL 2016
\usepackage[T1]{fontenc}\usepackage[T1]{fontenc}is not needed any more. So I do not include it.\textnormal{\textemdash}? It seems from your image that the comment is in typewriter and an em-dash might not even exist in that font.\textnormal{\textemdash}worked! if you like to post this as answer will accept it. sorry I was not clear about lualatex, but I showed the command I used which is lualatex.lualatexquestion
