Try %% it might work to escape.

put the string it in double quotes: "%{var} some string"

If in doubt, try converting a string to yaml in IRB

C:\Documents and Settings\a.grimm>irb
irb(main):001:0> require "yaml"
=> true
irb(main):002:0> "I'm giving it 110%!".to_yaml
=> "--- I'm giving it 110%!\n"
irb(main):003:0> exit
