If you're displaying this in a web browser, use the ® or ® HTML entities. The browser should interpret them as the correct character.

You could also try Array#pack.

puts [174].pack('U*')

That won't require any non-ASCII characters in your source code.

You have to declare the source encoding:

# coding: utf-8
p "®"

(just add the # coding: utf-8 line in your file to declare its encoding to utf-8)
