How would Chinese Dasher work?

We would not go directly for the ideograms, since there are too many of them. We have to build up sentences using a sequence of symbols each of which has small information content.

We can imagine two possible approaches.

1. Use a phonetic approach. Pin-yin is a standard method for writing chinese phonetically. Having obtained a pin-yin sequence, we could then if required have a probabilistic pronunciation-to-ideogram mapping also implemented within Dasher. This is how I envisage japanese Dasher working (with hiragana first, then kanji if required). This is exactly how Japanese people write Japanese in JWord or Jemacs.
2. Use a stroke-based approach. Have the writer build up the ideogram stroke by stroke, in the standard sequence that every chinese / japanese child has drilled into them when they are young. The displayed glyph on the screen could be "the character drawn thus far" or could be "the next stroke" or perhaps both on top of each other.
