@metabyter i think it is more technically correct to phrase the question as in a url, should i encode the spaces using %20 or + in the query part of a url? because while the example. Since it's not mentioned anywhere in. I am interested in knowing why '%20' is used as a space in urls, particularly why %20 was used and why we even need it in the first place.
If you look at rfc 3986 appendix a, you will see that space is simply not mentioned anywhere in the grammar for defining a url. As the aforementioned rfc does not include any reference of encoding spaces as +, i guess using %20 is the way to go today. 20 (unable to get local issuer certificate) asked 13 years, 5 months ago modified 1 year ago viewed 390k times
A bit of explaining as to what that %2520 is : The % character is encoded as %25. The common space character is encoded as %20 as you noted yourself. What is the difference and why should this happen?
