Tai-oan-ji: A Korean logic to writing Taiwanese

Tai-oan-ji is an attempt to develop a 'native' script for Taiwanese, and seems to have come about out of a desire to avoid both Chinese and western influences on writing (from the roman alphabet and Chinese characters, respectively). It is a phonetic script, with different elements (initial, vowel, final, tone) being represented within a squarish block.

This is strikingly similar to the way that Korean Hangul is constructed and it would be unsurprising if that system was the inspiration for this one. Like other efforts to devise new systems for writing Taiwanese, it has never been adopted by a significant number of people, but it is interesting nonetheless as an example of the decidedly undecided nature of the debate on written Taiwanese.
