Strange Icons

[KyleGobel]

I'm not sure what I'm missing or why things are rendering like this.

Thought this maybe a common one.

Everything looks fine except when responses don't have a schema.

Example:

An example css class that makes that:

zippy-empty[_ngcontent-grp-11] .zippy-indicator[_ngcontent-grp-11]:before {
    content: "—";
    font-weight: bold;
}

Not sure why this happening though (minus sign "-" being switched with whatever that symbol is)

Duplicate of #213 and #29

tl;dr
Just add <meta charset="utf-8"/> to your html
