right, i think the intent is to simply write it like you say it, even if it is different dialect. so the spellings won't match, but they aren't meant to. in this way they will more accurately convey what is being said.
i hear you on the unicode support, and communities online seem good. there's also an Esperanto variant of Shavian which is cool.
i may start with Shavian, and maybe do some quikscript for more artistic fun since it's also geared for writing cursive.
sometimes ppl think it's not worth stirring up more overt trouble, and just try to ride out the madness until the next admin while silently doing what you can to protect your own interests.
word, i'm with you. thanks for reigniting my interest in this! it really is so cool, and English could really use an update. XD
