How can I display accent characters in Neko with StablexUI Text?

[Tom]

Hi!

I would like to make localized GUI for an OpenFL, Neko application, with StablexUI, but the accent characters, like (öóőúéáűí) not showed up, just gibberish - from bad character encoding.
This happens if I use UTF-8 encoded XML, or from code, too.

But if I compile into Flash, the characters are correct.

So I think Neko can't handle correctly the UTF-8 encoded string.
Any idea to correct this?
And because StablexUI is macro based, doest it need to modify to handle these characters?

Thanks for any answers!
Tom
