Hardly a surprising choice! Congrats, Łukasz. (And never forget that at every Mac OS X upgrade I have to install the extended keyboard just so I can type that darn Ł. :-)

Heh, I *just* learned that, at least on macOS High Sierra (and probably going back several releases), on a US keyboard you can press and hold the ‘L’ (cap-L) key.  A little popup will appear like the attached image (if this doesn’t get stripped by Mailman).  Hit ‘1’ and the slashy-L will get entered: Ł.
