Oh COME ON. Where was this when my laptop died a month ago? I had to replace it asap and the previous kde slimbook was already out of stock. I got a great tuxedo, but this one is the same price and much better specs… I have the worst timing. Great news for everyone else though!

I did look it up, it’s great and faster than my layout for the big languages – German, French, Spanish and Italian – because the accented letters are on the third and fourth levels directly and not written via dead keys, but it’s harder to write most of the others like the Slavic languages (š, ů, ď, ł, ć, ̦ż, ą), Romanian (ș, ṭ, ă), Hungarian (ő, ű), Catalan ( · ), Azeri (Ə), Portuguese (ã), Turkish (ş, ţ, ğ, ı. İ) and Maltese (Ħ, Ġ). In EurKey each one requires Shift+AltGr+DeadKey+letter and a few are missing, while in my layout most of these require one less key. Of course this is not useful to most people, but I’m happy with it.

I agree, all these preferences (currency, time, date, measurements) shouldn’t need to fit in a determined locale box, but if you customize them it’s possible to run into issues. I believe choosing English (Ireland) might solve your issue? Either that or I have found a way to customize it way back and then forgot.
