Iqlau is written with a Logosyllabic system known as Qio'ao. Earlier this year, after discovering that Iqalu needed a way to be written with the Latin alphabet so it could be typed in on the computer, so I sat down at my computer, and spent and hour and twenty minutes and worked out a Latinized system for Iqalu that I tried out, and it worked perfectly, so that is what is officially used for writing Iqalu on the net and in books. For all else, the Qio'ao charcters are still used. The Latinized system for Iqalu works in the same way and has the same purpose as Chinese pin-yin.
