URLﾘﾝｸ(www.ietf.org)
URLに使用可能な文字を列挙したサイトを探しても見つからないから、
RFCを当たってみるしかないのかな。
httpurl = "http://" hostport [ "/" hpath [ "?" search ]]
hpath = hsegment *[ "/" hsegment ]
hsegment = *[ uchar | ";" | ":" | "@" | "&" | "=" ]
uchar = unreserved | escape
unreserved = alpha | digit | safe | extra
alpha = lowalpha | hialpha
lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" |
"i" | "j" | "k" | "l" | "m" | "n" | "o" | "p" |
"q" | "r" | "s" | "t" | "u" | "v" | "w" | "x" |
"y" | "z"
hialpha = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" |
"J" | "K" | "L" | "M" | "N" | "O" | "P" | "Q" | "R" |
"S" | "T" | "U" | "V" | "W" | "X" | "Y" | "Z"
digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" |
"8" | "9"
safe = "$" | "-" | "_" | "." | "+"
extra = "!" | "*" | "'" | "(" | ")" | ","
hostportの部分を飛ばして、パスのところだけ抜き出してみた。
これの意味を正確に把握するだけの知識はないけど、
見る限りだと円記号をパスに使うことはできない。
IEがRFCを無視して余計な世話をしているだけかと。
