If you have a byte array representing an UTF-8 string use the Java String constructor accepting a byte array and an encoding:

Java

String str = new String(utf8Bytes, "UTF-8");

If you really have a String object containing an UTF-8 string, you have to convert it first to a byte array:

Java

byte[] utf8Bytes = inputStr.getBytes("ISO-8859-1");

You can use any full 8-bit encoding in the above. It is just used to ensure that each single byte from the input string is copied to the byte array.

As is, this is non sense.
As 'á' is not ASCII, you need to understand a few things:
- what is ascii code
- what is ascii with codepages
- what is UTF encoding and UTF8
- you need to understand how Java handle char encoding.

Then you will decide what encoding you will use in your code. depending on encoding, the char is not the same.
