Subject: How to preserve line endings in strings with YAML?

Hi all,

Normally I would expect that
  YAML.load(x.to_yaml) == x
for all sensible values of x.

However, this does not seem to be the case if the string contains 
certain new line characters, for example:
  YAML.load("abc\r\n".to_yaml) # => "abc\n" ("\r" lost)
  YAML.load("\r\n".to_yaml)    # => ""      ("\r\n" lost)
  YAML.load("\n".to_yaml)      # => ""      ("\n" lost)

My question is: how can I configure YAML to preserve my line endings? 
I'm using Ruby 1.8.4-preview2 and have Googled for a solution without 
success. Note that the :UseBlock option to to_yaml does not help.

The reason that I need this functionality is that I would like to store 
a string which includes a digital signature in a YAML document. Any 
corruption of the line endings changes the string and consequently 
invalidates the digital signature.

Thanks very much,
