要更改字体，您可以为 #editor 添加 css 规则.或使用

To change font you can either add a css rule for #editor. or use

editor.setOptions({
  fontFamily: "tahoma",
  fontSize: "10pt"
});

但是 Ace 目前只支持等宽字体，而 tahoma 不是等宽字体，所以光标位置会出错.

But Ace only supports monospace fonts for now, and tahoma isn't monospace, so cursor position will be wrong.
