Seeing stuff like this, but knowing we can not get a unicode symbol for the https://en.wikipedia.org/wiki/Flourish_of_approval despite how ubiqitous it is in the Netherlands always frustrates me.
It doesn't seem like anybody ever filed the paperwork for it. (A search for "krul" on site:unicode.org doesn't turn up anything.) Unicode symbols don't just magically appear! Somebody has to do a bit of work to make it happen. If you're frustrated by a missing symbol, that somebody is probably you!
Perhaps we would have more of a chance if we make a collection of international differences in checkmark designs and propose that set of glyphs as a whole.
