there IS a chinese dictionary for DS as OSW just mentioned. it's called NewDictS. i just discovered it recently and it's actually not that bad. you are limited to using dictionary formatted for StarDict (some open source PC dictionary program) and it also requires one more little step before you copy it to your DS. it took a lot of searching but i found an old Stardict page with about 16 dictionaries (some E->C and some C->E.) from there it just takes a few minutes to get them ready for the DS.
there is no way to draw the character. you can input english and get definitions in chinese characters. i even found one dictionary (maybe based on the CEdict?) that has pinyin. you can also input in pinyin (only one character at a time and no intelligent guessing...you have to know the character you're wanting) and get english definitions.
it works pretty well if you already know a bit of chinese. but no matter what it's worth taking a look at rather than spending a LOT of money on a standalone dictionary (many of which are crap) when you already have a DS.
if you need any help setting it up, send me a PM. and kanji is the japanese word to desribe the characters. hanzi is chinese.
