Description

Json serialiation with Greek characters fails

To reproduce:

Object o1 = ["ΑΦΟΙ ΚΟΛΛΙΑ ΚΡΕΩΠΟΛΕΙΟ ΤΑΒΕΡΝΑ"]
println "o1=${new JsonBuilder(o1).toString()}"

Object o2 = ["ΑΦΟΙ ΚΟΛΛΙΑ ΚΡΕΩΠΟΛΕΙΟ ΤΑΒΕΡΝΑ", "Καλύβια Θορικού"]
println "o2=${new JsonBuilder(o2).toString()}"

Outputs:

o1=["\u0391\u03a6\u039f\u0399 \u039a\u039f\u039b\u039b\u0399\u0391 \u039a\u03a1\u0395\u03a9\u03a0\u039f\u039b\u0395\u0399\u039f \u03a4\u0391\u0392\u0395\u03a1\u039d\u0391"]
