I think it's because it's not bytes. Well, technically it's bytes of course, but conceptually once you decode bytes you no longer have bytes. You have that abstract idea of characters. And the only way to output that information into a file (which hold bytes) is by first converting it to bytes, and that requires encoding. It's just like a thought you have in your brain. I'm not aware of any way (yet) to output that in raw format -- must be encoded into typed, spoken, or signed language first. Even if most of what I write would be considered pretty raw. Isn't :raw mostly a way to use layers to say don't do CRLF conversion -- like the old use of binmode()? Oh, maybe not according to the docs. It's best to decode and encode all character data at program boundaries and stay away form Windows. -- Bill Moseley mose...@hank.org
