[texshop] feature request: show ASCII control chars

[G. M.-S.]

Thanks, Bruno.

Yes, I know BBEdit, and in fact I was suggesting showing *¿* as it does.

I use BBEdit for tasks like RE search and replacing, but I thought it would
be useful to stay within TeXShop for a simpler thing like this.

So you are right, it is not a pressing demand.

Best,

Guillermo
