"France and Italy are in Europe."
Translation:Francio kaj Italio estas en Eŭropo.
Unfortunately there is no such things as an universal character or letter. You might think of X, M or V as universal characters, but for many other people they are not, and might not even exist in their alphabets. Some other people (a lot of other people) again don't even use the Latin alphabet. The reason the ŭ ŝ ĥ ĵ etc. were selected is exactly because they are not found in any other language and thus would be less biased towards a certain people or group.
