"A".reverse() === "A"
"A".reverse() == "โ"
Where is your god now?!
Imagine, if you will. A world where string reverse changes the character codes of the string.
What beauty, what wonder would such a world have?
Destruction and despair. Developers unsure why their programs donโt respond correctly. Ships run aground on islands already overcrowded with those who were shipwrecked before. Signal antennas pointed towards the sun with itโs constant noise. Spacecraft whose exhaust melt to slag populated cities as people briefly scream their final terrors of pain and suffering.
This, is a world we should not want to live in. A world you can only find, in the Twilight Zone.
Yet we live in a world where
but sometimes "๐๐ฝ".reverse() == "๐ฝ๐"

Use a dynamically typed language and you won't have to: just override the default reverse() method on strings like a Real Programmer!

Iโm tempted to publish an NPM package to do so as a joke, but I fear that itโd get used seriously

Personally I'm not too fond of ligatures so I never enable any, but many folks do like them.
Edit: and just as a side note, ligatures are super common in many fonts, you just might not notice them. Here's some classic examples from the DejaVu Serif font, with and without a ligature:
