I just uploaded an initial draft of an article Balinese Script Notes. It lists the Unicode characters used to represent Balinese text, and briefly describes their use. It starts with brief notes on general script features and discussions about which Unicode characters are most appropriate when there is a choice.
The script type is abugida – consonants carry an inherent vowel. It’s a complex script derived from Brahmi, and has lots of contextual shaping and positioning going on. Text runs left-to-right, and words are not separated by spaces.
I think it’s one of the most attractive scripts in Unicode, and for that reason I’ve been wanting to learn more about it for some time now.
