There are no known or reported errors in RFC 3986.  There are a few
errors in implementations, but no consistency of such errors to
justify any changes to STD66.  If you think there is, then kindly
provide a list of such errors.

Are you talking about how to handle character encoding within
attribute values?  That is an HTML parsing issue.  The URI spec
does not define that because it is orthogonal to URI usage across
all of the different formats and implementations.  The URI spec
doesn't even come into scope until after the string is converted
from its data-entry format into a URI reference.
