In the anime "Faster, Kasumi, Kill, Kill", Ranma tries to write a 
kanji to contain the demon, but misses a stroke.  The spell is 
ineffective.  Says something about his kanje, doesn't it? ^_^	

Forgive me for my impudence, but I fail to see how that has any bearing at
all on whether or not he knows his kanji.  There are probably over five
hundred thousand different kanji, with only a fraction of them used
regularly.  Spirit wards would probably be a very specific kanji that few
outside of clergy would know.  You can't hold that against Ranma.  (I ask
you to recite the prayer for exocising a demon.  You can't, without
researching.)  That he was able to only miss one stroke, I feel, is a
testament to how intelligent Ranma is.
