[edit] Interpretation of percent-encoded octets
if i have a encoded sequence %7e%7e, how does it know it's ~~ or a unicode char with hex 7e7e? Xah Lee 03:42, September 10, 2005 (UTC)
- That's like asking what the letter "I" represents. It could represent the letter "I", the byte 0x49, the personal pronoun denoting individuality, the Roman numeral one…
- At the lexical level, if it is in a URI, then %7E%7E and ~~ mean the same thing: two instances of the tilde character (U+007E) and, simultaneously, two instances of the byte 0x7E. These characters and values, however, may be representing almost anything, depending on where in the URI they appear, and why. Maybe each tilde represents byte value 7E, and maybe the pair together is significant. Maybe not. So, you don't know, really. In order to figure it out, you need to know more about the context. How and why the sequence was produced? Is it HTML form data? Was the producer of this sequence following the guidelines of some URI scheme? — mjb 04:56, 10 September 2005 (UTC)
[edit] Added a reference table
Hey all, I just came to this article looking how to encode a % sign in a url string... noticed that the article couldn't tell me, just how to find out (which is arguably more encyclopedic) so I went along and added a table. Possibly needs a bit of rewording if it's decided to keep the table, else if you don't like it feel free to remove it =) Themania 15:12, 1 March 2007 (UTC)
