+ 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?
