@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. Sometimes the spaces get url encoded to the + sign, and some other times to %20. 照片的尺寸是以英寸为单位，1英寸=2.54cm ，通常x寸是指照片长的一边的英寸长度。 身份证、体检表等多采用小一寸22×32mm， 第二代身份证 26mm×32mm，普通一寸相.

As the aforementioned rfc does not include any reference of encoding spaces as +, i guess using %20 is the way to go today.
What is the difference and why should this happen?
