\Alpha doesn't print Capital Alpha, but \alpha prints undercase alpha??

[wm2015email]

Issue Summary

I just downloaded the Latest MathJax library 3.2.2. from nodejs. I noticed thart some of the Capital Greek letters don't work for some reason on my html page in a MathJax Equation, but all of the undercase greek leters work. See my webbrowser screenshot below: For example \alpha displays an undercase greek alpha chracter correctly, but \Alpha don't display a capital Greek Alpha character. See Picture below for example:

My webbrowser is the WebView2 UI Component in Microsoft .Net...

Any Idea how to fix this? It works ok in Typora Markdown editor...

Steps to Reproduce:

Here's my markdown code to produce the image above:

Name	Lower	Upper	English
Alpha	$\alpha$	$\Alpha$	A
Beta	$\beta$	$\Beta$	B
Gamma	$\gamma$	$\Gamma$	G
Delta	$\delta$	$\Delta$	D
Epsilon	$\epsilon$	$\Epsilon$	E
Zeta	$\zeta$	$\Zeta$	Z
Eta	$\eta$	$\Eta$	H
Theta	$\theta$	$\Theta$	Q
Iota	$\iota$	$\Iota$	I
Kappa	$\kappa$	$\Kappa$	K
Lambda	$\lambda$	$\Lambda$	L
Mu	$\mu$	$\Mu$	M
Nu	$\nu$	$\Nu$	N
Xi	$\xi$	$\xi$	X
Omicron	$\omicron$	$\Omicron$	O
Pi	$\pi$	$\Pi$	P
Rho	$\rho$	$\Rho$	R
Sigma	$\sigma$	$\Sigma$	S
Tau	$\tau$	$\Tau$	T
Upsilon	$\upsilon$	$\Upsilon$	U
Phi	$\phi$	$\Phi$	F
Chi	$\chi$	$\Chi$	C
Psi	$\psi$	$\Psi$	Y
Omega	$\omega$	$\Omega$	W

Supporting information:

• Please supply a link to a (live) minimal example page, when possible.
• If your issue is with the display of the mathematics produced by MathJax, include a screen snapshot that illustrates the problem, when possible.
• Check your browser console window for any error messages, and include them here.
• Include the MathJax configuration you are using, and the script tag that loads MathJax itself.

The capital Greek letters that are the same as Latin letters, like capital Alpha, do not get their own macros in standard LaTeX. So MathJax doesn't have \Alpha, \Beta or the other macros that are shown in red in your images. So this is the expected behavior for MathJax. You can, of course, define your own macros for \Alpha and the others.

See the documentation for how to define new commands from within the mathematics of your page, and the configmacros documentation for how to pre-defined them in your MathJax configuration.
