There are 4 use-cases IMHO, for a templating engine:
1) pure text-template. No escaping;
2) text-template to embed in some custom format
3) template generates HTML
4) template generates text, possibly HTML-like
I did not check what boost.mustache does, but from the documentation (
https://mustache.github.io/mustache.5.html ): “All variables are HTML
escaped by default. If you want to return unescaped HTML, use the
triple mustache: {{{name}}}.”. I understand “unescaped HTML” as “plain
text”. So thick mustaches {{{foo}}} would be #1.
If that's not the case (ie it can't produce plain text), that would
make boost.mustache completely useless for me.
I think you're right, and I got it wrong above.
If foo contains the text "" (w/o the dquotes),
then the template {{foo}} should expand to ">foo&bar/<",
while {{{foo}}} should expand to "" verbatim.
So that covers #4 (and there's no #3...), and #1, respectively.
But that leaves #2 uncovered I think.

So I still think escaping should be an independent / orthogonal dimension
from the templating proper.
