Graham It may be that that whilst string data processed by our LiveCode scripts and handlers is Unicode that is not the case with UI objects. I think that there is a chance that LiveCode is still using native encoding (Windows Code Page on Windows, ISO-8859-1 on Linux and the truly venerable MacRoman on OS X).
I’m not sure how to check but would imagine many people on the list do.
