Jeju/Keyboard
Existing resources
There has not been any keyboard layout developed for Jeju. This is a problem because although Jeju uses Hangul for writing, there is a sound retained Jeju that is not currently used in Standard Korean.
Since the vowel not in Modern Hangul, called "Arae-a"(아래아) is written ㆍ, native speakers have used the middle dot symbol(·) as a work-around.
Types of layouts
There are two classes of keyboard layouts developed for Korean, two-group and three-group layouts. They differ in how they classify the letters of Hangul, the Korean alphabet. Two-group layouts group Hangul letters into consonants and vowels. Three-group layouts group them into onset, nucleus and coda sounds. This document will provide a discussion of the two different types and which one is best suited for Jeju-eo.
