Arrow dingbats

[Chris]

Unicode has the arrow dingbats ⬅⬆⬇⬈⬉⬊⬋

in the range 2b05 with names like “LEFTWARDS BLACK ARROW"
conspicuously missing is the right arrow

The closest one can find is 27a1 “BLACK RIGHT ARROW"
➡

But everywhere I can see that has this arrow, it looks a lot different to the 
other arrows with a narrower body and head.

Whose fault is this, and who will fix it?
