Special characters are not allowed inside the query string. They must be replaced by a "%" followed by the ASCII code in Hex. E.g., "~" is replaced by "%7E", "#" by "%23" and so on. Since blank is rather common, it can be replaced by either "%20" or "+" (the "+" character must be replaced by "%2B"). This replacement process is called URL-encoding, and the result is a URL-encoded query string.
それは、入力フィールドの値として % を使用できないということですか?
