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

aphillips has just created a new issue for https://github.com/w3c/webauthn:

== Use of in-field metadata not preferred ==
6.4.2. Language and Direction Encoding
https://www.w3.org/TR/webauthn-2/#sctn-strings-langdir

> The first encodes a language tag with the code point U+E0001 followed by the ASCII values of the language tag each shifted up by U+E0000. For example, the language tag “en-US” becomes the code points U+E0001, U+E0065, U+E006E, U+E002D, U+E0055, U+E0053.

The above mechanism was introduced in this version of webauthn to address I18N's comment (w3c/webauthn#1526) about the need for language/direction metadata. It would be preferable to introduce separate metadata fields. It's unclear if this mechanism is a good idea vs. doing nothing, since presumably implementations might be created and thus constitute a backwards compatibility issue.
