Answer 1

Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read} and all was fine.

Answer 2

data = File.read("/path/to/file")

Answer 3

I think you should consider using IO.binread("/path/to/file") if you have a recent ruby interpreter (i.e. >= 1.9.2)

You could find IO class documentation here http://www.ruby-doc.org/core-2.1.2/IO.html
