simple_text_input_read seems a little on the verbose side, but between that and it being named read while used in an implementation of Read::read, yeah, I'll take it.

@dvdhrm @workingjubilee Do you think read should ignore non-printable characters instead of returning an error?

@workingjubilee

I think Err in that case is correct: we lost the input, effectively. There's lots of ways to suppress that kind of error if the programmer wants.

Thanks a lot for improving this! Some comments inline.

I really think we should suppress unknown scancodes. This is what TTYs on linux do, so I think we should follow.

There's at least one change we need to settle before we can ship this.
