Re: Encoding nightmare! Pls help!

John,

My first guess is that your code is working fine, it is just your
System.out.print() calls that are the problem.  You haven't specified
what character set to use when printing, so it will use the default
character set for your jvm.  This is necessary since java strings are
stored internally in ucs2 and java needs to convert to some other
character set when printing them out.

thanks,
