ps. the function I used was:

repeat for each char c in tData
add 1 to tc
get charToNum(c)
if it <> 9 OR it <> 10 Or it <> 13 AND it < 32 then exit repeat

return tc = length(tData)

Ummmm - that's not right.
Instead of
if it <> 9 OR it <> 10 Or it <> 13 AND it < 32 then exit repeat
it should be
if it <> 9 AND it <> 10 AND it <> 13 AND it < 32 then exit repeat
As it is, every character will pass that test - usually on the first and
certainly no later than the second sub-clause of the test.
I'd still expect this method to be faster than the Regex - but your test
will run somewhat faster than the correct equivalent would.
