Counting Chars By ASCII Part 2

I've come up with this:

on anotherOne
   put fld 1 into tString
   repeat with n = 1 to 30
     if (n >= 10 AND n <=12) OR n = 29  then next repeat
     put n & tab & charCount(n,tString) & cr after tList
   end repeat

   put tList into fld "chars"
end anotherOne

function charCount n,tString
   put length(tString) into oLen
   replace numToChar(n) with empty in tString
   return oLen - length(tString)
end charCount

Of course this won't find chars > 255, but then I have a question -

if you insert "set the useUnicode to true" at the beginning of it, it  
still works, however if you do the same with your handler, on my  
system, it takes four time longer, and produces no result. Without  
the useUnicode setting, surely we're only able to count chars with an  
ascii value <= 255...or have I misunderstood this ascii 1-byte, 2- 
byte stuff?
