The curious case of the disappearing Polish S

# Summary A Medium user reported being unable to type the Polish letter "Ś" on the platform, despite being able to type all other Polish characters. The bug stemmed from a combination of historical factors: Polish's use of nine diacritical marks, the lack of Polish-customized keyboards during Communist-era Poland when Western computers were imported, and legacy keyboard encoding systems that persisted for decades. Medium's engineers traced and fixed the issue, which had remained undetected because it required this specific convergence of linguistic and technological circumstances.
