"""
In the case of emoji, you've probably seen the failure mode of this process before! Because some emoji are actually ligatures of several simpler emoji, a font may successfully report support for the character while only yielding the components. So ����‍♀️ may literally appear as �� ��‍ ♀ if the font is "too old" to know about the new ligature. This can also happen if your unicode implementation is "too old" to know about a character, causing the styling system to accept a partial match in the font.
"""

Here the first emoji is broken as described, I see a black-and-white facepalm, some weird tofu character, and then the ♀ character. (The second one is intentionally "broken" to demonstrate.)
