Unfortunately, you're more than half right. The InputStreamReader and 
OutputStreamWriter classes do handle UTF-8 correctly. The readUTF and 
writeUTF methods in DataInputStream/DataOutputStream don't. This 
wouldn't be a problem if they were simply called 
readString/writeString instead. However, your comments about the char 
types are dead on.
