The World Unity Alphabet alphabet (WUA) was invented by Shane Gartner as a writing system that can be used to write virtually any language. You could call it his hope for the future where all nations of the world will be united in peace and harmony.
He used existing alphabets to construct the language into a uniform font, bringing together the idea of world unity (hence the name). The template he came up with is a circle with six triangular sections that looks sort of like a Trivial Pursuit "pie" piece, which he likes to think represents the six (inhabited) continents and their nations. It can also be two peace symbols stacked on top of each other. He borrowed characters from as many different languages as he could as an "original" design for each letter. He borrowed from some languages more than once, taking in account how many people speak them.
Because many languages have distinctions between similar consonants and vowels, (e.g. [o] and [ɤ]), W.U.A. uses diacritics ("moons") to distinguish between certain sound shifts.
The WUA can use any form of punctuation, depending on the language being written.
All human beings are born free and equal in dignity and rights. They
are endowed with reason and conscience and should act towards one another
in a spirit of brotherhood.

If you need to type in many different languages, the Q International Keyboard can help. It enables you to type almost any language that uses the Latin, Cyrillic or Greek alphabets, and is free.
