Special characters

Note: In Texinfo, the backslash is an ordinary character, and is entered without escaping (e.g. ‘The @code{\foo} command’). However, within double-quoted Scheme and/or LilyPond strings, backslashes (including those ending up in Texinfo markup) need to be escaped by doubling them:

(define (foo x)
  "The @code{\\foo} command..."
  ...)
