Ah, but what count does is just to return the number of values in an array and values may be empty strings.

And, personally, I would be very much confused if textSelections and selectedSubstrings returned different values because, in my understanding, selectedSubstrings is a kind of shorthand which is equivalent to...

$doc = Document.active
$sels = $doc.textSelections
$substrings = Array.new
foreach $sel in $sels
	$substrings.appendValue $sel.substring
end

exit $substrings

How about this? I don't think there is a standard way for that, though.

$sel = TextSelection.active
if $sel == undefined
	exit 'No open document or the focus in a non-text object (floating image or something else?)'
elsif $sel.length
	exit 'One or more characters (or in-line images) selected'
else
	exit 'Just a caret (zero-width selection)'
end
