So it seems that there is no way to map the Pinyin version of the pronunciation of Chinese words into Chinese characters directly:
What must be done is, in addition to spelling out the sound of the word in Pinyin, you must select the appropriate character out of a list of characters that match that sound/spelling.
What I'm wondering is, the max number of items that would appear in that list (roughly). For example, say that there are 10 words/characters that are all called
yī. Then there are just 10 characters in the list you'd have to select from when typing that in. Maybe there is only 1 matching character, I'm not sure.
Wondering what the rough estimate or scale is of how many character sets map to a single pronunciation. If it's like 5 or 10 max, or 100 or 1000 in some cases. That would be interesting to know.
