- How to write a UTF-8 file with Java?
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();
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 inside a try-with-resources Statement:
try (OutputStreamWriter writer =
new OutputStreamWriter(new FileOutputStream(PROPERTIES_FILE), StandardCharsets.UTF_8))
// do stuff
}
Try this
Writer out = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream("outfilename"), "UTF-8"));
try {
out.write(aString);
} finally {
out.close();
}
Try using FileUtils.write from Apache Commons.
You should be able to do something like:
File f = new File("output.txt");
FileUtils.writeStringToFile(f, document.outerHtml(), "UTF-8");
This will create the file if it does not exist.
All of the answers given here wont work since java's UTF-8 writing is bugged.

Since Java 7 you can do the same with Files.newBufferedWriter a little more succinctly:
Path logFile = Paths.get("/tmp/example.txt");
try (BufferedWriter writer = Files.newBufferedWriter(logFile, StandardCharsets.UTF_8)) {
writer.write("Hello World!");
// ...
}
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();
The Java 7 Files utility type is useful for working with files:
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.io.IOException;
import java.util.*;
public class WriteReadUtf8 {
public static void main(String[] args) throws IOException {
List<String> lines = Arrays.asList("These", "are", "lines");
Path textFile = Paths.get("foo.txt");
Files.write(textFile, lines, StandardCharsets.UTF_8);
List<String> read = Files.readAllLines(textFile, StandardCharsets.UTF_8);
System.out.println(lines.equals(read));
}
}
The Java 8 version allows you to omit the Charset argument - the methods default to UTF-8.
we can write the UTF-8 encoded file with java using use PrintWriter to write UTF-8 encoded xml
Or Click here
PrintWriter out1 = new PrintWriter(new File("C:\\abc.xml"), "UTF-8");
Below sample code can read file line by line and write new file in UTF-8 format. Also, i am explicitly specifying Cp1252 encoding.
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(
new FileInputStream("c:\\filenonUTF.txt"),
"Cp1252"));
String line;
Writer out = new BufferedWriter(
new OutputStreamWriter(new FileOutputStream(
"c:\\fileUTF.txt"), "UTF-8"));
try {
while ((line = br.readLine()) != null) {
out.write(line);
out.write("\n");
}
} finally {
br.close();
out.close();
}
}
