Unicode problem while writing out to a text file?
Feb 18th, 2008, 3:45am  
I've run into a little problem while writing a program to auto-generate French vocabulary lists for myself. I'm able to read unicode characters in and write them to the console just fine, but when I try to write a text file, something bad happens to any extended characters.

Here's a little code sample to illustrate:

String[] test = new String[2];

test[0] = "é, ö";
test[1] = "\u00EA";

println(test[0]);
println(test[1]);

saveStrings( "test.txt", test);


It prints"é, ö", and "ê" to the console very nicely, and then writes some square root symbols followed by other extended characters to the file.

Can anyone shed some light here? Am I missing some unicode output magic?

I can't say why saveStrings() doesn't work (i checked the processing source and it seems it should), but here's some code for you that will work (uses java.nio).  

Code:

import java.nio.*;
import java.nio.channels.*;

void setup() {
  String test = "é, ö \u00EA";
  try {
    FileOutputStream fos = new FileOutputStream(sketchPath("test2.txt"));
    FileChannel outfc = fos.getChannel();
    ByteBuffer bb = ByteBuffer.wrap(test.getBytes());
    outfc.write(bb);
    outfc.close();
  } 
  catch (Exception e) {
    e.printStackTrace();
  }
}

I don't really understand how it works, but it does. Thanks so much!
