Re^5: passing data structures from java to perl

That's really really bad advice. You can get encoding errors like that on the java side. Yeah, the bytes in memory are all that matter and you're fine to interpret, but on the way in and out, you're playing with things.

It's the same thing like binmode. You're affecting the data as the IO occurs to get into our out of memory. See...

http://www.docjar.com/docs/api/java/nio/charset/UnmappableCharacterException.html

I've run into this exact problem using the XML feeds for perlmonks while working in java.

Not sure what you're talking about. UTF-8 is a variable-width (multi-byte-if-needed) encoding that can encode the full unicode character set, so why should there be encoding errors, or an `UnmappableCharacterException`? An `UnmappableCharacterException` is thrown if a certain character can't be represented in the specified target encoding, but as all unicode characters can be encoded in UTF-8, this exception cannot occur. `UnmappableCharacterException`s may happen if you try to encode unicode data to Latin-1, for example, but not with UTF-8.
