I noticed today that tags can't contain characters with diacritics symbols (I tried to add the "túró" tag and I got the "tr" tag: the software just removed the unallowed characters without notice) so apparently we can't use the correct spellings when non basic Latin characters are used (i.e. crêpe, brûlée, spätzle, főzelék, lecsó, döner, frappé, Þorramatur, Kåldolmar).
Is that true? Is there a reason why only ASCII characters are allowed in tags?
By the way, I would never eat a dish in a restaurant if its name is misspelled - if the name is wrong, what about its ingredients or preparation? Cooking requires care about details.
