overline in markdown

[drom]

Overline is popular text attribute in datasheets.

Can be done with CSS:

o {
    text-decoration: overline;
}

<o>WR</o>

missing from markdown CSS

can be added as "combining overline" unicode caracter: ̅

I noticed that your method of doing overline doesn't work well with many fonts. W̅R̅ is what you see. I used <pre style="font-family: monospace;">W&#x305;R&#x305;</pre> to get this:

W̅R̅

Also, for some reason the things in your example ds that should be overlined are underlined, except for

R̅D̅ and W̅R̅
