What if there aren't enough spaces at the end of the row? Should excess non-space characters at the end be dropped or should wide character padding stop early?

That doesn't actually work very well as the ICU descriptions for those characters are essentially useless. We'd need to add a (possibly language-dependent) table that gives proper descriptions for those characters. If we do, I'm not sure it's something we'd want to go through the effort of localizing.
