This PR enhances the documentation for the
compareUtf8Strings()method by adding a concrete example. This example illustrates the nuances of comparing Unicode strings, particularly how characters represented by surrogate pairs in UTF-16 can compare differently than the lexicographical comparison of their UTF-8 encoding.This PR is in response to review comment firebase/firebase-android-sdk#7098 (review) and is a port of firebase/firebase-android-sdk#7113
