That's intersting

[Yuki~]

I was looking for japanese stuffs on wikipedia, and I found out something really intersting, I didn't know it.
That's what I found out:

There are a few hiragana which are rarely used. <b>Wi ゐ</b> and <b>we ゑ</b>.
They are on the ''wa/wo'' line, and I didn't know they existed. Then there was also some uses of these two hiragana...

<i>~ うゐのおくやま
u wi no o ku ya ma
(ui no okuyama)
The deep mountains of vanity

~ゑひもせす
we hi mo se su
(yoi mo sezu)
Shall no longer delude you </i>

It wasn't me who translated those lines, I got them on Wikipedia... ^^
But that's veeeery interesting, because I bought once a InuYasha's thing and there was a text and this (ゐ) hiragana there. I didn't know what this mean, but now I know what is this.. ^^

If anyone want to see where I got this, go to
this page.. ^^

Yep, they're obsolete. Just like when を is used as WO.
The katakana equivalents are ヰ(WI), ヱ(WE), ヲ(WO).

Obsolete in the way that they aren't actually used anymore at all is my understanding, the only time I have seen them is in a really old Japanese dictionary at a second hand book store
