get micron sign into a dialog menu

[Michael Doube]

Hi all

Just a fiddly little question:  I want to get a menu into a macro dialog
that lists units, mm, µm, nm, px.  To get the µm, I have this code:

var microns = fromCharCode(181,109);
var units = newArray("mm", microns, "nm", "px");

Then put into a dialog menu like this:

Dialog.addChoice("Units: ", units);

but instead of µm I get NaN in my menu.

Any suggestions?

This problem is due to a bug in the newArray() macro function. This bug
is fixed in v1.40e, or you can work around it using

   microns = fromCharCode(181,109);
   units = newArray("mm", microns, "nm", "px");
   units[1] = microns;
