Not a problem.  If you want to get the value of foo wrapped in parens,
but omit the parens if foo is undefined, you write:


>   http://www.google.com/search{??|term,num}{,&|term,num}

Currently {?foo|a,b,c} isn't supported: that's defect #11.

It's not about the template language's encoding: the template language
is defined in terms of characters.  It's about how characters written
from variables to the final URI get %-encoded.
