For some reason, reading in an entire file, for example with simple test code like this, doesn't appear read the whole file:

Try "rb" and "wb" as the 2-nd parameter to io.open().
Yes, that's that. I tested this code on a Unix-style file (the Lua manual) and since I ran it on Windows, I actually got a bigger file: LFs were transformed to CR+LFs.
Binary files were indeed truncated. Probably on first \0 found... Adding b is the way to go with binary files or if you want to preserve original EOL.
