Unicode string from concole methods

Hi there.

I would like to know what is the way to return a unicode string from a console method defined inside the engine.
Any atempt setting the string from script seems to be successful, but when defining a ConsoleMethod returning const char * values, all I get is non-readable characters.

I tried using getCopy8 of the StringBuffer class, but I am a little lost on how exactly to use it.
Is there an example in the engine that could give me a hint?

Thanks in advance for any kind of help,

Yannis
