Vowel characters are the following (or as near as i can come to it without a font):
|i, y||˙, v|
And i’ve dreamt up some pretty squigglies and swirls in there as well.
One problem remains, however, and that it the question of how to distinguish between voiced and unvoiced runes. Originally, as stated earlier, i used a vertical line on the left side of each character, but since none of the characters look right without this line, i must figure out another way to represent this. I was considering perhaps some sort of ˝ either above or to the left of the character to indicate that i was indeed voiced.
