UTF-8 issue in Java code

Question

I get the string “REL Д енÐ'Ð ° ÐÐ ′ instead of getting the “Calendars” in the Java code. How can I convert 'Ð ° Ð? ÐμнÐ'Ð ° ÑÐ 'in' Calendars'?

I used

 String convert =new String(convert.getBytes("iso-8859-1"), "UTF-8") 
 String convert =new String(convert.getBytes(), "UTF-8")

I believe your code is ok. It seems that your problem is that you need to perform a specific character conversion, and maybe your "real" input is incorrectly encoded. To test, I would do a standard CharSet step-by-step encoding / decoding to see where something breaks.

, http://docs.oracle.com/javase/1.6/docs/guide/intl/encoding.doc.html

, , :

//i suspect your problem is here - make sure your encoding the string correctly from the byte/char stream. That is, make sure that you want "iso-8859-1" as your input characters. 

Charset charsetE = Charset.forName("iso-8859-1");
CharsetEncoder encoder = charsetE.newEncoder();

//i believe from here to the end will probably stay the same, as per your posted example.
Charset charsetD = Charset.forName("UTF-8");
CharsetDecoder decoder = charsetD.newDecoder();

ByteBuffer bbuf = encoder.encode(CharBuffer.wrap(inputString));
CharBuffer cbuf = decoder.decode(bbuf);
final String result = cbuf.toString();
System.out.println(result);
