xtend - How to assign a char in Xtend?

Question

How can a variable of type char be assigned? I am looking for the Xtend equivalent of javas:

char c='?';

In Xtend the compiler reject all quotation marks like ' or " because they produce a String:

var char c='?';

^ Error: Incompatible types. Expected char or java.lang.Character but was java.lang.String

Xtext Version is 2.2

Since 2.4 you can write:

val char c = '?'

Currently you have to use '?'.charAt(0).
