I'm looking for a way to turn toggle the "comment" status of certain comments within a latex document. The idea is that throughout the document, including the preamble, there are specific commented-out lines that I can effectively toggle on and off, from comment to printed line. The following MWE shows my attempt to instigate this using a command, but unfortunately it just prints the % character:
% Compiles with XeLaTeX
\documentclass{memoir}
\usepackage{polyglossia}
\setmainlanguage{english}
\newcommand{\tcom}{\%} % I was hoping changing this as needed would work.
\tcom comment in preamble that can be toggled.
\begin{document}
% comment that should remain hidden.
\tcom comment that can be toggled.
\end{document}

Since you're using XeLaTeX you have thousands of characters you don't use in your document. Choose one that you can easily type (maybe with a shorthand in your editor). Here I use
ༀ
TIBETAN SYLLABLE OMIf you uncomment the line
\showcommentstrue
the chosen character will be ignored, otherwise it will act exactly like%
.
