Watch out for the case where the last character in the string is the one 
you are interested in; because there isn't an item after it, this gives 
the wrong result - I'd use

function charCount tText,tChar
  set the itemDelimiter to tChar
  if char -1 of tText = tChar then
    return the number of items in tText
  else
    return the number of items in tText - 1
  end if
end charCount
