Out of interest - why are you trying to do this? I ask because trying to do so may not be useful in future versions of LiveCode.

In LiveCode 7.0, all text is Unicode and there is no such thing as "non-Unicode text". There are ways to convert text to and from legacy 8-bit encodings (like MacRoman) when doing I/O to files/sockets/processes/etc but (in the engine at least) all text is Unicode.
