* <p>
|
||||
* 二维码编码有ECI模式和非ECI模式的情况之分，在ECI模式下第一个字节是用作编码标识，而非ECI模式下直接就是数据流。
|
||||
* ECI模式其实是更好的方案，这样子解码的时候可以根据标识采用不同的编码方式。而非ECI模式只能按照一种统一的方式处理了。
|
||||
* 但是由于部分设备不支持ECI模式，所以就出现了无法识别的情况。
|
||||
* 使用扫码桩/扫码枪，可能会出现\000026的字符。使用手机扫描、其他二维码解析软件扫描，则不会出现。
|
||||
* </p>
|
||||
*
|
||||
* <p>
|
||||
* ECI编码表可以看出UTF-8就是对应"\000026"（对应数字22）<br><br>
|
||||
* </p>
|
||||
*
|
||||
* <p> 总结建议：如果二维码内容全是字符，没有中文，就不用使用UTF-8等格式进行编码，只有使用中文等特殊符号才需要编码 </p>
