Kotlin with Intellij doesn't show non ascii characters

Question

When I try to print a special character like "?, ?, ü, á, é, etc..." with

fun main() {
    println("?")
}

Intellij outputs:

>Task :FirsttryKt.main()
?
BUILD SUCCESSFUL in 1s
...

How can I print the "?" or other non ascii characters?

Answer 1

It's a known bug.

As a workaround you can add -Dfile.encoding=UTF-8 in Help | Edit Custom VM Options and restart IntelliJ IDEA.
