I don't think that binary data should print as HEX as default. Binary data are stored as such in order to be used as binary data in an application (think of images, small media files, various sorts of binary patterns etc.) and not primarily intended for a terminal

Hi!

I agree with Peter, but this is  a patch that deals only with mysql command line client. It does not change, at all, data sent to the applications.

Fully verified.

Noted in 5.5.57, 5.6.37, 5.7.19, 8.0.2 changelogs.

The mysql client now supports a --binary-as-hex option that causes
display of binary data using hexadecimal notation (0xvalue). Thanks
to Daniël van Eeden for the patch.
