How do I escape a Unicode string with Ruby?

Question

I need to encode/convert a Unicode string to its escaped form, with backslashes. Anybody know how?

Answer 1

To use a unicode character in Ruby use the "\uXXXX" escape; where XXXX is the UTF-16 codepoint. see http://leejava.wordpress.com/2009/03/11/unicode-escape-in-ruby/
