and I wanna have this converted or outputet to-----> ex

which is the ascii code of 0x65 (=e) and 0x78 (=x) . But how can I do
this ?

test = 0x65 doesn't, test = "0x65" doesn't test = String(0x65) also
doesn't...

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

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