Java. Io. charconversionexception: Not an ISO 8859-1 character: XXX

This problem may be caused by text output from outputstream.

Response. setcontenttype ("Text/html; charsets = UTF-8");
//Response. getoutputstream (). Print ("text ");//This line of error
Response. getwriter (). Print ("Text");//Just replace it with this.
Response. getwriter (). Close ();
 

I personally think it is because outputstream outputs strings in bytes and needs to conform to the ISO 8859-1 encoding. However, the output string is UTF-8 encoded, so there is a problem. But I really don't think about the root cause.

Just replace it with writer. It may be because of the difference between inputstream and reader, outputstream and writer.
