I would keep "UTF-8" in the PREAMBLE. It does not matter much in the case of this case, but I would prefer to keep UTF-8 strict so that it's aligned with encoding in the handshake logic:

remoting/src/main/java/org/jenkinsci/remoting/engine/JnlpProtocol2Handler.java

Lines 129 to 133 in b7c0861

	DataOutputStream outputStream = state.getDataOutputStream();
	outputStream.writeUTF(PROTOCOL_PREFIX + getName());
	outputStream.writeUTF(o.toString("UTF-8"));
	outputStream.flush();
