Tried it out on my a text file containing:

"The King and Queen of Hearts were seated on their throne when they arrived,
with a great crowd assembled about them--all sorts of little birds and beasts,
as well as the whole pack of cards: the Knave was standing before them, in
chains, with a soldier on each side to guard him; and near the King was the
White Rabbit, with a trumpet in one hand, and a scroll of parchment in the
other. In the very middle of the court was a table, with a large dish of tarts
upon it: they looked so good, that it made Alice quite hungry to look at them--
`I wish they'd get the trial done,' she thought, `and hand round the
refreshments!'

But there seemed to be no chance of this, so she began looking at everything
about her, to pass away the time. "

And it worked fine with an added try catch, but worked fine without it just gave exception warning in the middle.
