问题 I found an explanation to decode hex-representations into decimal but only by using Qt: How to get decimal value of a unicode character in c++ As I am not using Qt and cout << (int)c does not work (Edit: it actually does work if you use it properly..!) : How to do the following: I got the hex representation of two chars which were transmitted over some socket (Just figured out how to get the hex repr finally!..) and both combined yield following utf16-representation : char c = u"\0b7f" This

From google webmaster tools I see some 404 errors domain.com/file.php?id=1 (404) Not found (Date) This url works ok but because of browser page decoding, the real (404) url is domain.com/file.php%3Fid%3D1 (this is what my browser displays in the url input when I click on google url) My first try was RewriteRule ^(.*)\%3F(.*)$ $1?$2 [R=301, L] to change %3F to ' ? ' but it does not work. It is confusing what is real and what is en/decoded.
