also my name is IJffdrie, not Ijffdrie as ij is a single letter and thus should be capitalized together
What? Hungarian has letters sz, zs, cs, ty, gy, ny, ly, but only the first is capitalised. Dutch is even weirder than I had thought.
officially both letters need to be capitalized, but almost no one does it, however my dad gets furious when they dont
in this case only IJ is with both capitalized since it actually is a single letter which does not appear on your keyboard so we use i and j represent it. letters like eu, au, ie, ei and ou only have one capitalized so it is Europa IJsland
