Terms: get_terms by name mismatches emoji

[kraftbj]

When assigning emoji-named terms to a post, it appears the post processing will match some emoji characters incorrectly. So far, it appears it occurs within get_terms.

Steps to duplicate:
Write a post and attempt to add two flag emoji (e.g. Mexico and Germany) as individual tags.

Expected: Both terms are assigned.

Actual: Only one.

Another method: Create two tags of just the two flags, then assign the second one created. The first one created will be assigned instead.

It doesn't happen for all emoji, but I didn't isolate if it by plane, etc.

@kraftbj Before testing this, can I get more information about your database charset and collation?

Thanks @boonebgorges utf8mb4 / utf8mb4_unicode_ci .
