Summary: Angstrom, Parts per thousand, Parts per Ten-Thousand cannot be displayed.
Prior efforts: Searched Google and Detexify.
But that command
\AAdid not work. Such as
Only the Percent works (
Commands for Parts per thousand (
$\permil$) and Parts per ten-thousand (
$\textpertenthousand$) renders these respectively:
$\textperthousand$, $\permil$, $\textpertenthousand$.
Now, my questions are;
Could I use them in MathJax? (By any other command?)
(Seems like the "text mode" is causing some trouble. Maybe they have some "math mode" counterpart?).
Could I use them by any means other than MathJax? (Say using Markdown and Basic HTML)?
