I initially planned to put a TL;DR here, but it's the best bug analysis I've seen in months - a pleasure to read! - so I'm leaving it for others to savour. The very same bug used to be present in early Windows mobile GPU drivers - with global hotkeys making it impossible to enter Ł (with Intel GMA 950) and Ć (with ATI Catalyst). Being a Polish geek, I used to earn lots of free dinners from frustrated friends who were forced to copy-paste those letters on their brand new laptops. Funny how the same bug recurs in different types of software due to an obscure locale-dependent edge case - and it's much less known than, for example, the Turkish dotted/dotless I.
