When I try to input utf8 characters in my Linux terminal window via input or just in REPL, I get ?? or ??? (depending on number of bytes). print input, print to-string input do the same.

On the other hand "view" handles utf8 just fine. For example

view [ f: field button "Click" on-action [ print get-face f ] ]

prints every utf8 character as expected.

By the way, windows terminals (both cmd.exe and cygwin) get and print utf8 correctly.
