Here's what I know about tengwar, Tolkien's invented script. Many people know it as elvish, but you can use it to write any language, with a bit of modification. I hope this tells you what you need to know.
The best website I've found for information is at.mansbjorkman.net/intro.htm
It taught me a lot of what I know. It's got lots of lovely detail and a variety of modes (if mine doesn't suit you)
