It worked nicely in the message box:

	put numToCodepoint(0xE7) into tPrecomposed
	put  "c" & numToCodepoint(0x0327) into tDecomposed
	set the formSensitive to true
	put tPrecomposed <> tDecomposed into tResult
	set the formSensitive to false	
	put return after tResult
	put tPrecomposed = tDecomposed after tResult
	put tResult

Produced:
	true
	true

But when I tried it in my test script, setting the formSensitive to true didn't seem to have the same effect:

on mouseUp
	startTest "Unicode1"
	put numToCodepoint(0xE7) into tPrecomposed
	put "c" & numToCodepoint(0x0327) into tDecomposed
	assertEqual tPrecomposed, tDecomposed
	endTest
	
	startTest "Unicode2"
	put numToCodepoint(0xE7) into tPrecomposed
	put "c" & numToCodepoint(0x0327) into tDecomposed
	set the formSensitive to true
	assertNotEqual tPrecomposed, tDecomposed
	set the formSensitive to false
	endTest
end mouseUp

The result was:

	Test Unicode2
	Assert #1
	Expected ç
	Actual ç 
	Unicode2 Failed

I suspect that I am probably doing something wrong such as trying to set formSensitive in a handler.
