Depending on the line you want to check, you can use the 
'formattedText' property - which will return you the data from the 
field with hard returns where it has wrapped naturally. So to get the 
number of characters for the first line of text in a field:

  put length(line 1 of the formattedText of field 1)

Keep in mind that the problem with calculating the number of characters 
is that proportional fonts will mess up your calculations. 

But hopefully this puts you on the right course,
