Printing Unicode characters from Groovy.

Seems to work out of the box. At least on Linux.

examples/groovy/unicode.groovy

def latin_letters = "Hello World"
println latin_letters

def hungarian = "Álom ló és ő egy ügyes ökör."
println hungarian

def hebrew = "שלום עולם"
println hebrew

def arabic = "السلام عليكم"
println arabic
