+ is a special representation of a space in URL encoding but it's the one-or-more collective char in perl.  My guess is that the intent is to replace plus's with spaces which requires escaping the +, How about

$line =~ tr/\+/ /g;

where I have added the g to get them all.

But what the devil is the thingy (missing char) repeated at least once? Should it not have produced a compile error or a least a warning?  Was the -w switch used?
