Almost certainly.

Without knowing the encoding, you can't recognise the "\r\n".

Well, it sounds to me like you don't really need to convert the bytes
at all. If you assume that the "\r\n" are encoded as bytes 13 and 10
respectively, you should be able to do it all without ever treating it
as text data.

If you *have* to treat it as character data, using 8859-1 is probably a
good bet. In theory I believe it doesn't contain characters for bytes
128-139, but in practice I believe the encoding treats them as Unicode
128-139.

Alternatively, just cast each character to a byte using CByte.

I've just had a look at the yEnc spec, and unfortunately it seems to
have been written by someone who doesn't appreciate the difference
between binary data and text data, and also doesn't understand that
ASCII doesn't have any values > 127...
