Re: [webauthn] Use of in-field metadata not preferred (#1643)

> Remove the custom encoding, at least the language tag. The language tag seems ignored by browsers now, but the direction marks seem to work. This would reflect reality, while leaving open the door to make changes in L4.

Direction marks at the _end_ of the string don't do anything (unless the rest of the string consists of weak or neutral characters. This is not an effective mechanism for indicating the base paragraph direction and it does require modifying the input string to accomplish it. If you remove the mechanism for in-string encoding, remove _all_ of it. Implementations can insert bidi formatting characters as needed to accomplish proper bidi support and should do so if metadata is not an option, but they should do so at the proper (normal) location(s) in the string, not dangling from the end.
