Thanks guys, except now I'm having a new problem. My array of lines is
now containing empty strings that actually report a length of zero.
This would be fine, except when I try to filter the array to get rid
of these empty lines,
[array filterUsingPredicate:[NSCompoundPredicate
notPredicateWithSubpredicate:[NSPredicate predicateWithFormat:@"SELF
LIKE %@", @""]]];
this code has no affect. These empty strings have a length of 0 so
they would have to be just empty strings. Other filtering predicates
work fine. Is this a problem with the predicate?

If the length of this mystery string is 1 and it's not a space,
what is it???
Use -characterAtIndex:0 and print the returned unichar using the
"%x" format.
Another sometimes-handy trick is to create a mutable copy and call
CFStringTransform with kCFStringTransformToUnicodeName.
You should also look at -getLineStart:end:contentsEnd:forRange: if
you're parsing lines of text, as it takes into account a variety of
possible line endings, not just \n.
