Hi,

disregarding what is in the user's guide, I recommend
using the escaping workaround

#set( $Q = '"' )
#set( $B = '\' )
${Q}foo
${Q}!foo
${B}${Q}!foo
${B}${B}${Q}!foo

to obtain anything you literally want. (The implementation
using the escaping character does not always do what you
would expect - a bug!).

P.S. I also use $TAB and $NL many times to enhance my output.
The values are obtained via a context tool having a
decodeUrl("%09") and "%0a" method.

Cheers,
Christoph
