In 4.10.19.4 URL-encoded form data, The application/x-www-form-urlencoded encoding algorithm, it says:
> For each character in the entry's name and value, apply the following > subsubsteps: > > If the character isn't in the range U+0020, U+002A, U+002D, U+002E, > U+0030 to U+0039, U+0041 to U+005A, U+005F, U+0061 to U+007A > then replace the character with a string formed as follows: > Start with the empty string, and then, taking each byte of the character > when expressed in the selected character encoding in turn, > append to the string a U+0025 PERCENT SIGN character (%) followed > by two characters in the ranges U+0030 DIGIT ZERO (0) to > U+0039 DIGIT NINE (9) and U+0041 LATIN CAPITAL LETTER A > to U+0046 LATIN CAPITAL LETTER F representing the hexadecimal value > of the byte (zero-padded if necessary). > > If the character is a U+0020 SPACE character, replace it with a single U+002B > PLUS SIGN character (+). This means, U+9670, encoded as "¥x89¥x41" in Shift_JIS, must be encoded as "%89%41", and shouldn't be "%89A"? thanks, -- NARUSE, Yui nar...@airemix.jp
