Hi,
I would like to run some Racket programs in the macOS Terminal (racket
foo.rkt bar1 bar2), and keep staying in the Racket REPL when my code has
completed. Is that possible?

Works like a charm. Thanks!
Maybe that "21.1.1 Interactive Mode" chapter should mention that "-it"
solution?

Sorry, but I'm not quite happy yet. ;-)
When I get the ">" prompt, the definitions made in my hello.rkt seems to be
gone. I get "cannot reference an identifier before its definition". How can
I avoid that definitions and data get lost?

If I enter this in the REPL in my macOS Terminal
(string->list "hei")
then I get '(#\h #\e #\i), as expected, but if I replace "hei" with "høy",
the input line suddenly looks like this
(string->list "h\U+FFC3\U+FFB8y")
and what I get back is '(#\h #\y). The letter "ø" has been stripped away.

My Terminal "Advanced" tab also says "Unicode (UTF-8)".
When I run the PicoLisp REPL, then I have no translation and stripping,
"høy" is entered as "høy", it seems.
