[cifs-protocol] character escaping in DN and canonicalName

hi Dochelp,

According to RFC 4514 and articles like
the characters ' ', '"', '#', '+', ',', ';', '<', '=', '>', '\' are
escaped with a leading '\', while other characters can be escaped as hex
values like "\0a". For canonicalName, '/' must also be escaped, for
obvious reasons.

My question is: is there anywhere a list of which characters are
canonically escaped in the hex form?

That is, I suppose a carriage return is always escaped as "\0d", and an
'A' is never escaped as "\41". But I don't know whether, for example,
"ā" ('a' with macron) is included in a canonicalName or DN string as
"\C4\81" or as the plain UTF-8 "ā".
