Alicja Raszkowsa nerdsniped me into inquiring into pangrams in languages other than English. The Polish Wikipedia page has an extensive list. I was interested to learn that in Polish, a pangram must contain each of ‘z’, ‘ż’, and ‘ź’. Note that this is not completely obvious. A Spanish pangram must contain both ‘n’ and ‘ñ’, but need not contain both ‘o’ and ‘ó’, as those are the same letter. Possibly fun exercise: write a computer program which, given a sequence of pangrams in an unknown script, emits the list of letters in that script. For Spanish it should emit both ‘n’ and ‘ñ’, but only one of ‘o’ and ‘ó’.
