Change your code as below. My test file can conv to UTF-8, view in

What is "Reflection UTF-8"?

Not a bad job there, but I have to wonder why you ruined the indentation and
still are flouting the naming conventions. Code should be readable.

Also, it is exceedingly bad that you eliminated logging. You should keep the
logging. Switch to java.util.logging if you don't like log4j or don't care to
add the JAR, but for Pete's sake keep the logging. Yikes.

Here's a pop quiz for you - given that few code examples I've seen use the
idiom I did of a separate try block for opening the Reader and Writer from the
one for using them, why do you think I bothered?

Is it better or worse than the common idiom, or simply a matter of style and
more power to you for whichever?

View in IE the font is ok.
