Question

I am writing into a java file through

               FileWriter fstream = new FileWriter("someFile.java");
                BufferedWriter out = new BufferedWriter(fstream);
                out.write(strContents);
                // Close the output stream
                out.close();

but after writing I found it appended some special characters in shape of box like [], but those special characters are only visible in specific text editor like EditPlus.

How to avoid those special characters while writing or is it specific to some editors only.

Answer 1

My advice would be to avoid using FileWriter completely. It always uses the platform default encoding, which is rarely a good idea.

I would suggest using FileOutputStream wrapped in an OutputStreamWriter – then you just need to specify an appropriate encoding, such as UTF-8. Obviously you’ll still need to use an editor which supports UTF-8, and you may need to tell it the encoding… but at least you’ll have code which always writes in the same way, regardless of OS and system properties.
