Problems with binary strings in Ruby

Question

I am currently trying to make my Ruby script output the following:

"\x41" * 28 "\x42\x13\x40\x00"

My code is:

puts "\x41" * 28 "\x42\x13\x40\x00"

instead of outputting it as you might expect it outputs: AAAAAAAAAAAAAAAAAAAAAAAAAAAAB‼@

I know that this is the "translated" values but how do I avoid this translation? I have been looking into .pack() but I could not figure it out.

Thanks in advance.

How about

puts "\\x41" * 28 + "\\x42\\x13\\x40\\x00"

or

puts '\x41' * 28 + '\x42\x13\x40\x00'

Case 1 works because \\ is an escape sequence meaning a \ while case 2 works because the literals inside '' only check for the \' and \\ escape sequences.
