Have you seen my ongoing efforts towards a unified 2D drawing system called Canvas (http://wiki.flightgear.org/Canvas). It basically allows drawing 2D shapes (with OpenVG) and text (using osgText::Text). As it uses osgText for textrendering, supporting UTF-8 is very easy. I just tried it and with changing a single line of code now also using UTF-8 is supported. Currently only drawing inside an existing (PUI) dialog is possible, but the idea is to slowly implement the current functionally in Nasal and get rid of the hardcoded PUI widgets. Only some code for mouse/keyboard interaction with Nasal will be needed. In contrary to using some hardcoded GUI system (PUI, osgWidget, etc.) this approach would give much more flexibility and also the means of modifying and creating new widgets without the need to touch any core code. With the Canvas system every type of widget would be possible, so that also things like submenus can be realized. Another advantage of the Canvas approach is that it is heavily using the property tree and therefore is already fully accessible from Nasal code and also configurable with the existing xml formats. Switching to another scripting language or adding support for a new one, I think would be far too much work and not worth the efforts.
