The curious case of the disappearing Polish S — Medium Engineering — Medium

The curious case of the disappearing Polish S — Medium Engineering — Medium:

A few weeks ago, someone reported this to us at Medium:
“I
just started an article in Polish. I can type in every letter, except
Ś. When I press the key for Ś, the letter just doesn’t appear. It only
happens on Medium.”
This was odd. We don’t really special-case any language in any way, and even if we did… out of 32 Polish characters, why would this random one be the only one causing problems?

Turns
out, it wasn’t so random. This is a story of how four incidental
ingredients spanning decades (if not centuries) came together to cause
the most curious of bugs, and how we fixed it.
