I'm familiar with the character, but I've never seen the series. While I have seen people those traits in people with Autism, their not very common, as StarTrekker had already pointed out.
If you're looking for Japanese Animated works that feature characters who are unmistakably Autistic, then I find Death Note to be a good example of how wide the spectrum can get while still sharing common base traits.
They are as follows
Light Yagami

L

Near

Mello

They are all extremely Autistic, but there not in your face about it, the show never brings it up, so it's left up to you the viewer to connect all the dots.
Interestingly enough, Shinigami appear to be the poster children for Sociopaths in the series, especially Misa's Shinigami, who demonstrates the lengths Sociopaths will go to in order to defend those they've grown to love.
If you haven't watched Death Note yet I highly recommend that you go check it out, it's both entertaining and interesting all at once.
