Please see the following images. Thanks.



would you add -Dfile.encoding=UTF8 in arduino.l4j.ini or arduino_debug.i4j.ini file ?

@hanj-kim Yeah~ It works. Thank you
Is there any possible issue with having this option as default? If not, I'd like to suggest to add it to launch parameters of the next version.
@feikname probably no problem with having this option. Arduino IDE / compiler use UTF 8, there are no problem that change encoding to UTF8 Arduino IDE use UTF8
