Chinese does have autocorrect and spell check based on statistical analysis of how often words are next to each other. Another benefit of such a system is that it's similar to romance languages where when characters are used in different languages, even though they are pronounced differently there is some mutual intelligibility. I don't speak french or portuguese but when reading the ingredients list (which they always put a sticker over the English section to show the local language) I'll use my Spanish knowledge to know what's inside.
