The Hungarian alphabet is pretty funny. There are many letters with diacritical marks (sometimes incorrectly called accent marks. There are no accent marks in Hungarian, as the stress always falls on the first syllable, without exception). Some of the marks also exist in Portuguese, others can be found in German or French.

Here are two words that contain every diacritical marks in Hungarian:

árvíztűrő tükörfúrógép

It's basically nonsensical, but literally it means: "flood resistant mirror drilling machine" (I told you it doesn't make sense...)
