JavaScript function golf, 77 bytes (non-competing)

var s=i();var x=0;for(var i1=0;i1<sl(s);i1++){x+=schca(s,i1);}console.log(x);

I made this for you!

Yes, you got it right, it's my own function golf again. It recently got a string functions update.

The language was created after the challenge, so it's non-competing.

Validity source:

>>> var s=i();var x=0;for(var i1=0;i1<sl(s);i1++){x+=schca(s,i1);}console.log(x);
Hello World!

Bonus score:

>>> var s=i();var x=0;for(var i1=0;i1<sl(s);i1++){x+=schca(s,i1);}console.log(x);
var s=i();var x=0;for(var i1=0;i1<sl(s);i1++){x+=schca(s,i1);}console.log(x);
