Hm. I think this is all up to personal preference. At the moment ASCII characters are used for all default styles if I remember correctly, though not quite sure why. You can manually customize widget characters fairly easily though, so if you could make an example of how it would look I'd gladly look into it!

I don't think the checkbox widget can be customized without changing the logic in this case.

As for the ASCII characters, the box widgets does not use ASCII characters for its border, so I don't think this will be an issue.

Also, using a single character instead of three gives more space, which is a huge benefit imo since you can only fit so many characters on average displays.

Actually, it can! It's not the cleanest widget in terms of implementation, but it's still customizable the same way. I used this pretty ugly piece of code to mock up what it would look like inside a completely un-styled mockup window:

{                                                                                                                 
  ptg.Checkbox()                                                                            
  .set_char("checked", "▣") 
  .set_char("unchecked", "☐"): "Already registered?" 
}

I'm not sure I like this as a default style, for one main reason. As you can see on the second screenshot below, the character is small enough that it gets almost completely hidden when an average sized mouse cursor is over it. This hides its current state as well, which I don't find optimal.

I find it too small in general, so while it is a nice looking character it feels like it does the job less than [x] does. Though if you don't care about these concerns, you can use the code above (or the proper configuration APIs) to set it so.

I am planning to add support for more out-of-the-box configurations for things other than `Container` and `Window`, probably using some `chars` class.
