<span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;">本人在网上搜索，看到有使用javascript做unicode编码转换的，感觉很好玩，所以拿来使用的。</span><br style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;" /><span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;">这个功能有目前测试了两种：</span><br style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;" /><span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;">1）unicode互相转换，例如\u4e2d\u56fd转换成字符，支持中文和英文；</span><br style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;" /><span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;">2）URL编码的解析，例如众所周知的%20是表示空格，还有%24，%33，%44，%62等等；</span><br style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;" /><span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 25.200000762939453px;">我相信，只要你试试上面的字符进行解码，你就会知道他们之间关系，如何表示字符，数字，字母。</span>
