The list of categories on the left (and can be customized with the … button at the top-left): Is there any API to get that list of category names and the code points they encompass? They're different than the standard Unicode code point blocks? If so, is it available on iOS?
These categories don't appear to be available from any of the unicode.org documents I've seen, but then they host a ton of data, and most of it is beyond my need.
