Markup inside words

Hi, currently the markup inside words are rendered. See attached image below for math $ and italic *.

For now, we can use escape to force the character as literal, like CA\$30 and AA\*BB. But it writes and looks horrible, especially on $ signs for notes on money/price.

So I wonder if there are any better solutions. Alternatively, should the markup be rendered only if they are at word-boundary instead of inside the words, just like some other markdown flavours did.
