Special Characters In Latex

KaTeX Math Examples

Inline math (with $): The quadratic formula is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Display math:

$$\int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$

Another example of inline math (with $): A simple fraction is $\frac{1}{2}$.

Using \\( ... \\) for inline math: The derivative of $f(x) = x^2$ is \\( f'(x) = 2x \\).

Using \\[ ... \\] for display math: \\[ \sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6} \\]

Desm --- $Hello!$ example:

$\begin{array}{l}⌀\text{ vs. }\varnothing \text{ as }𝒜\text{ vs. }𝒜\text{!"\#\$\%\&’()*+,-./0123456789:;<=>?@ABC...Z[]^\_‘abc...z{|}~—–}\\ \text{∅︀}\end{array}$

$\KaTeX$ VS MathJax: Which will win?

$$Hello, TeX!\\ \mathrm{Aa123} \mathit{Aa123} \mathsf{Aa123} \mathsfit{Aa123} \mathtt{Aa123} \mathbb{Aa123} \mathscr{Aa} \mathcal{A} \mathfrak{Aa} \sqrt{\frac12+\left(\frac34\right)}$$

$\begin{array}{l}Hello,TeX!\\ \mathrm{Aa1}Aa123𝖠𝖺\mathrm{𝟣𝟤𝟥}𝘈𝘢123𝙰𝚊\mathrm{𝟷𝟸𝟹}𝔸𝕒\mathrm{𝟙𝟚𝟛}𝒜𝒶𝒜𝔄𝔞\sqrt{\frac{1}{2}+\left(\frac{3}{4}\right)}\end{array}$

I think $\mathbf{\KaTeX}$ and $\mathrm{MathML.}$ both tied.

Why?

Because of the rendering issues!
