Symbol polyfill uses "codePointAt"/"fromCodePoint" which are not available in IE

[rluba]

I'm submitting a bug report

• Library Version: any (as of 44ee5ed)

• Browser: IE any (tested in IE 11)

• Language: all

Current behavior: The Symbol polyfill uses codePointAt. But this function is not available in IE11 (see codePointAt on MDN) and therefore needs to be polyfilled as well.

The same goes for fromCodePoint.

Expected/desired behavior: Polyfill codePointAt and fromCodePoint to support IE without requiring additional polyfills.

This breaks: Array.from("abc")
