I use “the number of words in myString = 0” to test whether a line of text

But a line of text I pasted from elsewhere contained an invisible character
whose charToNum value is 202, and this was counted as a word by my script.
Is there a better way to test for a line of text that has no visible characters?
Here's where the "trueword" keyword comes in handy:
put the number of truewords in line x of fld y
It will ignore invisible and whitespace characters.
