What do these two commands ( \mathaccentV for pdflatex and \Umathaccent for {xe|lua}latex ) do exactly and how to use them (or how are they used)? As an example, could anyone give an example of how to use them to construct right arrows above math symbols, such as, e.g., a⃗ (except that the small let...

Consider the input \documentclass{acm_proc_article-sp} \begin{document} \texttt{``foo''} \end{document} using the most recent acm_proc_article-sp.cls , which I believe to be version 3.2 and which you can take, e.g., from https://raw.githubusercontent.com/tewalds/CMPUT663Survey/master/acm_pro...

I correct myself: I find it difficult... Probably, you mean ex rather than em, to match the height of the font.
Anyway, even if it's solved, the problem of how to get X into the PDF text layer remains.

A picture of X wouldn't result in X in the text layer of the PDF file generated. Moreover, I find it difficult to size-scale it automatically if needed.

In the old times of mathptmx , we wrote stuff such as \documentclass{article} \pagestyle{empty} \usepackage{mathptmx} \begin{document} Let \(\mathcal{X}=\{X_1,\ldots,X_n\}\). \end{document} and got from pdflatex a fancy calligraphic math X, which was sufficiently fancy to be visibly distinct...

What is the proper™ way to obtain a variable-size parallel operator to be used in the prefix position? If I see it right, stmaryrd 's \bigparallel already does the job for pdflatex , but how about [xe|lua]latex ? My attempts so far are cumbersome: \RequirePackage{ifxetex,ifluatex} \newif\ifxetexorlu...
