fix: \char support for >16-bit Unicode characters (#3006)

* fix: \char support for >16-bit Unicode characters

`String.fromCharCode` only supports Unicode characters up to 16-bit.
`String.fromCodePoint` from ECMAScript 2015 supports all Unicode code points.
Unfortunately, IE doesn't support the latter, so use former as fallback.

Fixes #3004
