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

This isn't the OP's question, but if you have just a single byte (not in an array) and want to make a string out of it, use chr

c = 65
=> 65
c.chr
=> "A"
c.chr.class
=> String
