X11 display server : X11.app on macOS "sierra"

I telnet into my Indy running IRIX 5.3, and start a winterm with display output to the Mac.

When I start to type into the winterm window, I get this:

Some special characters work (^L clears the screen, ^H erases, ^D closes the window), but most characters are echoed back as 3 character garbage. 'enter' is garbled as well. In the screenshot I typed "ls<enter>". The 'You have mail' text and the prompt string are good, so I think text output from the Indy is good.

What's happening here, is the Mac sending UTF to the poor old Indy?

NB: the Indy is running pretty stock IRIX 5.3, with ~ 40 patches (probably the recommended/required set), but no freeware, tgcware or other add-ons.

OK, I fixed it but I don't understand why. It's the 'Option keys send Alt_L and Alt_R' checkbox:
