Hello,
Hopefully this will be useful for teachers creating materials and students interested in phonemic script.
I've set up
http://www.phonemicchart.com with an online phonemic script keyboard. No software installation required, no special fonts needed. And it's free!
If you haven't yet learned the phonemic chart, there's also a "flashcard" type application to help you memorise the characters:
