When I open up a binary file in Vim, it displays a bunch of gibberish. One would expect it to display a bunch of 1s and 0s. Why is this?

One does not simply Vim into Binary. –  Snesticle Nov 7 '12 at 22:27

If you are using UNIX you can use the hd or hexdump command to dump out the the file in HEX and printable characters. –  HeatfanJohn Nov 7 '12 at 22:29

Excellent question.

Text editors don't open files and show binary. They typically read files with ASCII or Unicode encoding.

Here's some examples of how ASCII encoding works:

Basically the way it works is, it reads the first number of bytes, and then interprets that collection of bits as a certain character, which is what you're seeing on your screen.

However, if you want to show binary (or hex) in Vim, you can, by doing something like this:

That makes a lot of sense. Thanks! –  David Sawyer Nov 8 '12 at 5:04
