Hmm that is interesting. I don't have time right now to check into this further (or search the mail list archives), but I just tested and found this to be true for double quotes. Single quotes behave correctly, though, so you can use them as a work around method.

Input:
-------------------
"\n": [% "\n" %]
"\\n": [% "\\n" %]
"\\\n": [% "\\\n" %]
'\n': [% '\n' %]
'\\n': [% '\\n' %]
-------------------


Output:
-------------------
"\n": 

"\\n": 

"\\\n": \

'\n': \n
'\\n': \n
-------------------
