I've tested it and it seems to work pretty well. In the code page

	https://en.wikipedia.org/wiki/Symbols_and_Pictographs_Extended-A

The first U+1FA7x get matched, but U+1FAEx do not, there is some weirdness going
on there because thats a problem I already had with my rules. It's not really an
issue but I wanted to mention it anyways. 

For example these are among those that aren't matched:
 🫡🫣🫢🫠🫤

Thanks for the inspiration with the replace tags combined with the meta rules. I
wasn't really a power user before, we have pretty well trained bayes filters and
you guys have pretty good defaults already. 

Cheers,

Jona Müller
