I’m not sure if this is a brainfart of mine, or a bug, but I can’t get a literal asterisk in my markdown. The following:
md`I want a *literal \*asterisk*`
shows as " I want a literal asterisk* " instead of “I want a literal *asterisk” (here in the forum is does work as expected).
The quick fix employed, btw:
md`I want a *literal ${html`*`}asterisk*`Hmm. This looks like a bug in our Markdown library:
Glad you found a workaround. I would expect a double backslash to work, also, but I think we need to patch Marked to fix that.
Possibly related?
Is it possible to include a code snippet within a markdown block?
I would like to express something like:
Please use the myObjectType for this purpose,
but the markdown interpreter fails for this.
Sure thing - that’s a different issue, with thankfully a simpler fix 
md is a tagged template literal - it’s a function (md) and a new JavaScript feature (those backticks). So, like other strings in JavaScript - if you were to create a double-quoted string, and you wanted to put double quotes in that string, you need to escape them:
x = "They said "hi" I think" // an error
// Instead you want to escape those:
x = "They said \"hi\" I think" // works
Since template strings use the backtick as their start & stop symbols, to use them inside of a markdown string, you’ll need to escape them the same, with \. For your example, it’d be like
md`
Please use \`myObjectType\` for this purpose
`
You may also use <code>myObjectType</code>.
