Perpendicular Symbol Is Verbalized as "Bottom"

[NV-Codes]

MathCAT Version

MathCAT-0.6.6 (NVDA Add-On)

Issue

The perpendicular symbol ($\perp$) is verbalized as "bottom" for terse verbosity and as "is bottom" for medium/verbose verbosity for both SimpleSpeak and ClearSpeak.

Expected Behavior

MathCAT should verbalize $\vec{A} \perp \vec{B}$ as "vector cap A (is) perpendicular to vector cap B," much like it verbalizes $\vec{A} \parallel \vec{B}$ as "vector cap A (is) parallel to vector cap B." MathCAT should also call the symbol "perpendicular to" or "is perpendicular to" in Navigation Mode (in parallel with its verbalization of $\parallel$).

The Unicode that is generated by TeX for $\perp$ is U+22A5 which Unicode says is "UP TACK {base, bottom}". The correct Unicode symbol is U+27C2 : "PERPENDICULAR {orthogonal to}".

The presents a quandry: say the wrong thing for U+22A5 because that is what users might get, or say the right thing because users of other software will generate the correct symbol. I suppose TeX input is more likely. Thoughts?

This once again seems that it might be an issue with Markdown converting LaTeX to MathML, both by GitHub and Pandoc. It seems that they both might rely on the same converter, as both also fail to convert expressions like $i \omega t$ ("i," "omega," "t") correctly. I am not sure what the converter is that both GitHub and Pandoc seem to use, but perhaps issues could be opened there for the $\perp$ symbol and for generation of inaccessible/incorrect MathML (issue jgm/pandoc#325); when I try to find the GitHub page for "Markdown," I simply get the GitHub Flavored Markdown Spec sheet. Would you know where these issues could be reported?

Someone told me that github uses MathJaX. Maybe an older version of it because there are some differences.

I've reported the bug to:

• pandoc: Bad Unicode mapping for TeX input "\perp" jgm/texmath#247.
• MathJaX: \perp is mapped to the wrong Unicode code point mathjax/MathJax#3322
• KaTeX: \perp is mapped to the wrong Unicode code point KaTeX/KaTeX#4011
• mathlive: \perp is mapped to the wrong Unicode code point arnog/mathlive#2576

Thank you!

Closing as the problem lies elsewhere.
