解决js url传递中文乱码

传递url中汉字用encodeURIComponent（）转换文utf-8
在传递页面中用Utf8ToUnicode （）再转换为汉字
Utf8ToUnicode :function (strUtf8){
          var bstr = "";
          var nTotalChars = strUtf8.length;        // total chars to be processed.
          var nOffset = 0;                                        // processing point on strUtf8
          var nRemainingBytes = nTotalChars;        // how many bytes left to be converted
          var nOutputPosition = 0;
          var iCode, iCode1, iCode2;                        // the value of the unicode.
 
          while (nOffset < nTotalChars)
          {
                  iCode = strUtf8.charCodeAt(nOffset);
                  if ((iCode & 0x80) == 0)                        // 1 byte.
                  {
                          if ( nRemainingBytes < 1 )                // not enough data
                                  break;
 
                          bstr += String.fromCharCode(iCode & 0x7F);
                          nOffset ++;
                          nRemainingBytes -= 1;
                  }
                  else if ((iCode & 0xE0) == 0xC0)        // 2 bytes
                  {
                          iCode1 =  strUtf8.charCodeAt(nOffset + 1);
                          if ( nRemainingBytes < 2 ||                        // not enough data
                                   (iCode1 & 0xC0) != 0x80 )                // invalid pattern
                          {
                                  break;
                          }
 
                          bstr += String.fromCharCode(((iCode & 0x3F) << 6) | (         iCode1 & 0x3F));
                          nOffset += 2;
                          nRemainingBytes -= 2;
                  }
                  else if ((iCode & 0xF0) == 0xE0)        // 3 bytes
                  {
                          iCode1 =  strUtf8.charCodeAt(nOffset + 1);
                          iCode2 =  strUtf8.charCodeAt(nOffset + 2);
                          if ( nRemainingBytes < 3 ||                        // not enough data
                                   (iCode1 & 0xC0) != 0x80 ||                // invalid pattern
                                   (iCode2 & 0xC0) != 0x80 )
                          {
                                  break;
                          }
 
                          bstr += String.fromCharCode(((iCode & 0x0F) << 12) |
                                          ((iCode1 & 0x3F) <<  6) |
                                          (iCode2 & 0x3F));
                          nOffset += 3;
                          nRemainingBytes -= 3;
                  }
                  else                                                                // 4 or more bytes -- unsupported
                          break;
          }
 
          if (nRemainingBytes != 0)
          {
                  // bad UTF8 string.
                  return "";
          }
 
          return bstr;
