discrepancy in unicode character lengths in quill

Steps for Reproduction

1. check https://codepen.io/khaled4vokalz/pen/YzqWjgv?editors=0011
2. even though "ő".length === 2 quill considers it as length 1 when we do quill.getLength() but for an emoji e.g. "😀".length === 2 quill considers it as length of 2 when we do quill.getLength()
3. even though quill.getLength() returns 1 for ő, if I try to create a delta with ő and check delta.length() that returns 2. This is quite confusing.

Expected behavior:

• as JS returns same length for both the characters quill should do the same

Actual behavior:

• quill.getLength() returns 2 for ő and quill.getLength() returns 3 for 😀. quill should have a consistent behavior regarding the length that it calculates

Platforms:

Chromium: 81.0.4044.138, Ubuntu 20.04

Version:

1.3.6
