Converting a Byte Array to a String in Ruby

In Converting a Byte Array to String with Buffer in Node.JS I mentioned about Node.JS Buffers, and how they're a way to serialise an array of bytes into a JSON format.

As Ruby is my preferred scripting language, I wanted to document how to convert this back to a String with Ruby, too.

Let us assume that we have the following data:

[
  104, 116, 116, 112, 115,
  58, 47, 47, 119, 119,
  119, 46, 106, 118, 116,
  46, 109, 101
]

We can follow grosser's solution (bearing in mind David J's comment):

bytes = [
  104, 116, 116, 112, 115,
  58, 47, 47, 119, 119,
  119, 46, 106, 118, 116,
  46, 109, 101
]
puts bytes.pack('C*').force_encoding('UTF-8')
# 'https://www.jvt.me'
