The point of having a standard is to know which ones to deny. Make a study over a wide range of documents about the characters that are used the most, see if there are alternatives to the characters that don't make it, etc... This is unlike the HN ban on emoji, which I think is more of a political decision than a technical one. Most people on HN use systems that can read emoji just fine, but they decided that the site would be better without it. This would be more technical, a way to balance inclusivity and technical constraints, something between ASCII and full Unicode.
