Hi Please refer to section 19.1.2 of RFC 3261 which talks about character escaping requirements. Also if your quetion is intended for URI then refer section 2.4.3 of RFC 2396 which talks about space escaping for URI.
RFC 2396 section 2.4.3 says The space character is excluded because significant spaces may disappear and insignificant spaces may be introduced when URI are transcribed or typeset or subjected to the treatment of wordprocessing programs. Whitespace is also used to delimit URI in many contexts. space = <US-ASCII coded character 20 hexadecimal> regards Abhishek Dhammawat Aricent ________________________________________ From: [email protected] [[email protected]] On Behalf Of Iñaki Baz Castillo [[email protected]] Sent: Friday, February 20, 2009 9:55 PM To: [email protected] Subject: [Sip-implementors] About hexadecimal un-escaping Hi, I've realized that in URL hexadecimall escaping, space is converted to "+", this is: "'Stop!' said Fred" => "%27Stop%21%27+said+Fred" But I've read nothing about this space escaping in SIP, so the same text escaped for SIP would be: "'Stop!' said Fred" => "%27Stop%21%27%20said%20Fred" This is, using %20 as space. Am I right? Thanks a lot. -- Iñaki Baz Castillo _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
