this ?

test = 0x65 doesn’t, test = “0x65” doesn’t test = String(0x65) also

If you have this in an array, you can use Array#pack

eg.

a = [0x65, 0x78].
a.pack(“U*”)

This will work for multibyte unicode strings as well.

What exactly is this supposed to mean? This is not valid Ruby:

$ ruby -ce ‘test = 0x65 0x78’
-e:1: parse error, unexpected tINTEGER, expecting $
