How to write a UTF-8 file with Java?

Question

Hi there,

I have some current code and the problem is its creating a 1252 codepage file, i want to force it to create a UTF-8 file

Can anyone help me with this code, as i say it currently works... but i need to force the save on utf.. can i pass a parameter or something??

this is what i have, any help really appreciated

var out = new java.io.FileWriter( new java.io.File( path )),
        text = new java.lang.String( src || "" );
 out.write( text, 0, text.length() );
 out.flush();
 out.close();

Answer 1

Instead of using FileWriter, create a FileOutputStream. You can then wrap this in an OutputStreamWriter, which allows you to pass an encoding in the constructor. Then you can write your data to that.

Answer 2

Try this

try {
        Writer out = new BufferedWriter(new OutputStreamWriter(
            new FileOutputStream("outfilename"), "UTF8"));
        out.write(aString);
        out.close();
    } catch (UnsupportedEncodingException e) {
    } catch (IOException e) {
    }

Answer 3

var out = new java.io.PrintWriter(new java.io.File(path), "UTF-8");
text = new java.lang.String( src || "" );
out.print(text);
out.flush();
out.close();

Answer 4

Try using FileUtils.write from Apache Commons.

You should be able to do something like:

File f = new File("output.txt");
FileUtils.write(f, "Contents", "UTF-8");

This will create the file if it does not exist.

Answer 5

All of the answers given here wont work since java's UTF-8 writing is bugged.
