in thread Extracting lines starting with a pattern from an array

If you suspect that, you might try looking at the raw input data. For example, on *nix start with this

 $ od -cx input-data.txt > raw-input-data.txt

and look at the output file.

    As an added bonus, od is part of the PerlPowerTools suite so you don't even have to rely on it being supplied as a binary by your O/S.
