Java convert Windows-1252 to UTF-8, some letters are wrong

Question

I receive data from a external Microsoft SQL 2008 database (I make queries with MyBatis). The data is encoded as "Windows-1252".

I have tried to re-encode t

Answer 1

Obviously, textoFormado is a variable of type String. This means that the bytes were already decoded. Java then internally uses a 16-bit Unicode representation. What you did, is to encode your string with Windows-1252 followed by reading the resulting bytes with an UTF-8 encoding. That does not work.

What you need is the correct encoding when reading the bytes:

byte[] sourceBytes = getRawBytes();
String data = new String(sourceBytes , "Windows-1252");

For using this string inside your program, you do not need to do anything. Simply use it. If - however - you want to write the data back to a file for example, you need to encode again:

byte[] destinationBytes = data.getBytes("UTF-8");
// write bytes to destination file here
