Ruby: create a String from bytes

Question

I would like to build a string from a byte value.

I currently use:

str = \" \"
str[0] = byte

This seems to work fine but I find it

Answer 1

If bytes is an array of Fixnum's you could try this:

bytes.map {|num| num.chr}.join

or this:

s = ''
bytes.each {|i| s << i}
