Question

a lot of sites like google and wikipedia encode non-english characters in hex with a leading % sign. I looked for a tool that I could pipe URLs into it and, when such %AA strings are met, will translate these signs back to utf so that I can read them.

既然我找不到,我就把自己写进了正文,我想与大家分享,或许你会认为它有用:

#include <stdio.h>
int main()
   {
        char c;
        unsigned int i;
        while (!feof(stdin))
        {
                if (0==fread(&c,1,1,stdin)) break;
                if (c!= % ) putchar(c);
                else
                {
                        if (scanf("%X",&i)==1) putchar(i);
                        else putchar( % );
                }
        }
        return 0;
}

使用实例:

# echo "http://he.wikipedia.org/wiki/%D7%A2%D7%9E%D7%95%D7%93_%D7%A8%D7%90%D7%A9%D7%99" | ./dumpHex

results:

在VC++:

string dec = URLDecoder::decode(url)

PHP:

$d = urldecode($u)

Java:

String dec = URLDecoder.decode(url,"UTF-8");
