Causes and solutions of garbled characters

1. Cause of garbled characters:

Since the data is garbled character encoding format in transmitting and receiving process caused by the inconsistency.

for examples:

Input 11--> represents the binary 3 
         -> represents the hexadecimal 8 9 
         -> in hexadecimal represents 17

　　Here are 11 of the same input, but because the band is not the same, the value represented is not the same.

Similarly, a string of bytes is encoded in the underlying code, due to the different encoding formats, such as encoded in UTF-8 encoding format to iso8859-1 encoding format can not be resolved, so that the string is not unfolded the original string.

2. Character garbled solution

2.1 garbled first encoding, decoding is performed

User.getUserCount userCount = String (); 
// garbled string format conversion according to the error code to the original code sequence of bytes 
byte [] BS = userCount.getBytes ( "iso889-1"); 
// original word section code sequence using the correct encoding format for encoding, converted to the correct character 
userCount = new String (bs, " utf-8");
