Dear Roger, because in when unicode is used in real life, utf8 etc then
text ⊂ binary John Knightley On 2020-02-21 20:21, Costello, Roger L. via Unicode wrote:
Hi Folks, There are binary files and there are text files. Binary files often contain portions that are text. For example, the start of Windows executable files is the text MZ. To the best of my knowledge, text files never contain binary, i.e., bytes that cannot be interpreted as characters. (Of course, text files may contain a text-encoding of binary, such as base64-encoded text.) Why the asymmetry? /Roger
