Richard Suchenwirth 2001-03-16 - Here's an uncompleted but working utility from The Lish family that converts a string of 7-bit ASCII to a string of Unicodes of Japanese hiragana, katakana, and (some few) Kanji. Still under construction, but feel free to grab and paste it. If you have improvements, just edit this page.

Normal-size hiragana (lowercase) and KATAKANA (UC) are all included (even the rare VU). Compound syllables like /kyou/ from Tokyo still await a better solution than spelling them out kiyou, and ignoring the smallness of the /yo/. The ambigous syllable /ji/ is not included, choose "di" or "zi". (One might allow ji for the more frequent "zi", maybe?)

I fixed some of the hiragana, I think. --Anon

Kanji are a problem for itself. Excluding for the moment non-unique spellings, just which to choose is a difficult question. I put in some at the beginning and supply the proc japlish:map, so the user can add what he wants. Not elegant, I admit. Anybody have a kanji word frequency list?
