Subject: [Sip] any restrictions on characters in user part of sip uri?

From: [email-masked]

the syntax of user part of sip uri is:

user = 1*( unreserved / escaped / user-unreserved )
user-unreserved = "&" / "=" / "+" / "$" / "," / ";" / "?" / "/"

escaped is %hexhex and can thus be used to include any character in
user.  is it really so that there is no restrictions on what chars may
be include in user using escaped?  for example, is %0000 valid in user?
if so, it makes implementations "interesting".
