Java: Encode String in quoted-printable

Question

I am looking for a way to quoted-printable encode a string in Java just like php\'s native quoted_printable_encode() function.

I have tried to use JavaMails

To use this MimeUtility method you have to create a ByteArrayOutputStream which will accumulate the bytes written to it, which you can then recover. For example, to encode the string original:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStream encodedOut = MimeUtility.encode(baos, "quoted-printable");
encodedOut.write(original.getBytes());
String encoded = baos.toString();

The encodeText function from the same class will work on strings, but it produces Q-encoding, which is similar to quoted-printable but not quite the same:

String encoded = MimeUtility.encodeText(original, null, "Q");
