copied!<p>Assuming your data is in an array like so (each element is a byte, and further, from the description you posted, no larger than 127 in value, that is, a 7-bit ASCII character):</p> <pre><code>array =[104, 101, 108, 108, 111] string = array.pack("c*") </code></pre> <p>After this, string will contain "hello", which is what I believe you're requesting.</p> <p>The pack method "Packs the contents of arr into a binary sequence according to the directives in the given template string".</p> <p>"c*" asks the method to interpret each element of the array as a "char". Use "C*" if you want to interpret them as <em>unsigned</em> chars.</p> <p><a href="http://ruby-doc.org/core/classes/Array.html#M002222" rel="nofollow noreferrer">http://ruby-doc.org/core/classes/Array.html#M002222</a></p> <p>The example given in the documentation page uses the function to convert a string with Unicode characters. In Ruby I believe this is best done using Iconv:</p> <pre><code>require "iconv" require "pp" #Ruby representation of unicode characters is different unicodeString = "This unicode string contains two characters " + "with codes outside the ASCII code range, " + "Pi (\342\x03\xa0) and Sigma (\342\x03\xa3)."; #printing original string puts unicodeString i = Iconv.new("ASCII//IGNORE","UTF-8") #Printing converted string, unicode characters stripped puts i.iconv(unicodeString) bytes = i.iconv(unicodeString).unpack("c*") #printing array of bytes of converted string pp bytes </code></pre> <p>Read up on Ruby's Iconv <a href="http://ruby-doc.org/core/classes/Iconv.html#M001164" rel="nofollow noreferrer">here</a>.</p> <p>You might also want to check <a href="https://stackoverflow.com/questions/144380/ruby-how-to-break-a-potentially-unicode-string-into-bytes">this question</a>.</p>
