I’m actually complaining about more “advanced” features like hiding text (see my comment above) or zalgoing it.

And of course endless variations of skin color and gender of three people in a pictogram of a family or something, which is purely a product of a specific subculture that doesn’t have anything in common with text/charset.

If unicode cared about characters, which happens to be an evolving but finite set, it would simply include them all, together with exactly two direction specifiers. Instead it created a language/format/tag system within itself to build characters most of which make zero sense to anyone in the world, except for grapheme linguists, if that job title even exists.

It will eventually overengineer itself into a set bigger than the set of all real characters, if not yet.

Practicality and implications of such system is clearly demonstrated by the $subj.
