COPYing Unicode text

[Richmond]

I have managed (on a PPC Mac !!!) to copy
Unicode text out of a field onto the computer's clipboard
in such a way that the text and all its font and
unicode characteristics are preserved on pasting into
Abiword using a very simple script:

on mouseUp
   select the text of fld "ABC"
   copy the selectedText of fld "ABC"
end mouseUp

what I need to know is:

1. Whether this will work on:

1.1. Mac INTEL,

1.2. Windows XP,

1.3. into Microsoft Word (which I do not own).

sincerely, Richmond.
