I have a string containing byte data.
How can I perform an in-place conversion to ascii string?

1What sort of an ascii string do you want to see? A bit string ("0101110110"), hex ("0AFC43"), or just something marshalled into ascii to decode somewhere else?Brent.Longborough– Brent.Longborough2009-02-05 14:32:55 +00:00Commented Feb 5, 2009 at 14:32

Another way to play with binary data is String#unpack.

Thanks - unpack('H*') did the job.

suppose the binary data is a representation of arabic text.. (text which i'm receiving as some giberrish like
قرآن.. how do I unpack it to look like it's original arabic (ie using some arabic encoding or something)?

Is there a JavaScript equivalent to this?
You can do so via using base64 which is a fairly universal way.
require 'base64'
str = Base64.encode64(data)

data needs to be convertible to String for this to work. Try, for example: irb(main):002:0> Base64.encode64(1234) TypeError: can't convert Fixnum into String
if u have a binary string lets say something like:
s = "01001101011011110111000101110101011001010110010101110100"
and u wanna convert it back to ascii text in Ruby u can do like:
s = "01001101011011110111000101110101011001010110010101110100"
(0..s.length-8).step(8) do |i|
print s[i,8].to_i(base=2).chr
end
Hope this will help someone :)
