Convert File with known encoding to UTF-8

Question

I need to convert text file to the String, which, finally, I should put as an input parameter (type InputStream) to IFile.create (Eclipse). Looking for the example or how to

Answer 1

You need to specify the encoding of the InputStreamReader using the Charset parameter.

                                    // ↓ whatever the input's encoding is
Charset inputCharset = Charset.forName("ISO-8859-1");
InputStreamReader isr = new InputStreamReader(fis, inputCharset));

This also works:

InputStreamReader isr = new InputStreamReader(fis, "ISO-8859-1"));

You can get the default charset - which is comes from the system the JVM is running on - at runtime via Charset.defaultCharset().
