Calling strictEncodeURIComponent with some specific values cause an error in FF 3.6.

strictEncodeURIComponent('abcdefg()') // -> Error: invalid string escape mask 8

I hotfixed this by replacing the escape-function that is passed into replace with:

function(val) {return escape(val);}

Firefox 3.6, seriously? we're at 21. twentyone!

Sure, we don't like it either, but in one of our products we embed that browser (or xulrunner actually). And it's not that easy to upgrade.

let me get this straight, your fix is replacing

.replace(/[!'()*]/g, escape)


.replace(/[!'()*]/g, function(v){return escape(v); })

and that's it?

yep, that's it. It seems like FF 3.6 has some limitations in accessing native functions, I suppose this issue: documentcloud/backbone#2417 falls into the same category.

well, that's easy enough. I'll include that in the next version

great, thanks!
