Hi Keita

So far, none.

But with upcoming LaTeX dated 2019/10/01, they will get accepted
in so far as the suitable font support has been loaded with declared font 
encodings.

See

https://github.com/latex3/latex2e/blob/develop/base/doc/ltnews30.tex

specifically

https://github.com/latex3/latex2e/blob/764d6c44eae4e89325618fd9cd76a11d88af4921/base/doc/ltnews30.tex#L224-L265

Best,

Jean-François
