It's not only possible, that is exactly what is at the end of r. When
you are having such a problem, it is easier to see what the string
actually contains by doing one of the following:

1) puts "-->#{some_var}<---"

2) p r

which is the same as:

puts r.inspect

Here is an example:

str = "hello
world"

p str

--output:--
"hello\nworld"

And of course the newline makes a difference in the file name. You can
test that yourself:

some_file = "html.htm"

File.open(some_file) do |f|
puts f.read
end

Once you get that to work with a file on your file system, try adding a
\n to the end.
