As far as I can tell, it's just standard UTF-16, using the byte order  
of the host platform.

I don't know much about future plans, except that unicode  
implementation will be significantly enhanced. UTF8 is supported now  
through use of the uniencode() and unidecode() functions. So, for  
example, if I want to import a UTF8 file, I would simply read it in  
(using a binary, not text, read) to a variable, then encode it to  
UTF16 like this:

on mouseUp
   answer file "Choose a UTF-8 file to read in."
   if it is empty then exit mouseUp
   put url ("binfile:" & it) into tRaw

   set the unicodetext of fld "display" to \
       uniencode(tRaw,"UTF8")
end mouseUp

Then when you want to write a unicode field out to UTF-8 do something  
like this:

on mouseUp
   ask file "Save file as..."
   if it is empty then exit mouseUp
   put "binfile:" & it into urlname
   put unidecode(the unicodeText of fld "typing","utf8") into url  
urlname
end mouseUp

Hope this helps.
