No; a string contains a series of codepoints from the unicode plane, representing natural language characters (at least in the simplistic view, I'm not talking about surrogates). These can be encoded to different binary storage representations, of which ascii is (a common) one. > What I am looking for is a general way to just copy the raw data > from a "string" object to a "byte" object without any attempt to > "decode" or "encode" anything ... There is "logically" no raw data in the string, just a series of codepoints, as stated above. You'll have to specify the encoding to use to get at "raw" data, and from what I gather you're interested in the latin-1 (or iso-8859-15) encoding, as you're specifically referencing chars >= 0x80 (which hints at your mindset being in LATIN-land, so to speak). -- --- Heiko.
