As long as I use it internally for intermediate processing, I can do what I want. For now it is just a convenient way to represent variable size integers up to 31 bits (in fact I use it to represent 32 bit signed integers, but the two highest bits are equal). Of course if I still use it to represent something else thzn codepoints in some published data or text, I will rename it and won't keep the same charset label. But it's highly probable that this will not be the most efficient representation (due to its byte-oriented splitting), and a more compact or easier to process serialization could require an alternate encoding scheme (or transfer syntax). __________________________________________________________________ << ella for Spam Control >> has removed Spam messages and set aside Newsletters for me You can use it too - and it's FREE! http://www.ellaforspam.com __________________________________________________________________ << ella for Spam Control >> has removed Spam messages and set aside Newsletters for me You can use it too - and it's FREE! http://www.ellaforspam.com
