Unicode isn’t meant to replace all typesetting like LaTeX. For example, I can’t make proper horizontal fractions (as opposed to slashed like ⅝ or ⁹⁄₁₆) that are normal in my part of the world because that would be too much scope creep. Even the TeX logo is not really doable (Markdown with ASCII: TEX, Unicode ᵀᴇˣ).
An imperfect solution is adding ̅ U+0305 COMBINING OVERLINE above everything. For example, it does not sit at consistent height (√4̅a̅c̅) and Windows renders it incorrectly (centered to the right edge of the character, not its center).
This is how I’d render the numerator using Unicode only:
𝑏² ± √4̅𝑎̅𝑐̅
A correct Markdown interpreter can improve the look ogf the superscript:
𝑏2 ± √4̅𝑎̅𝑐̅
Nope, it looks like a basic vector graphics editor, think Inkscape, PowerPoint or whatever is built into their animation/effects software. They just used straight horizontal lines for the fraction and the bar of the square root.

So they had to use something “fancier” like TeX so they must’ve known about suoerscriots and the like
