I'm fairly sure キャラクター (or the shorter キャラ) is a more common word choice than 登場人物...~?
Also I do notice the grammar structures here are a lot more complicated than the sorts we usually see... for beginner-friendly-ness rewording might be needed. Though the fruit one is straightforward enough as-is.
Maybe I'm doing something wrong, but I don't like how the auto parser works. It parses every word, even when there's a name or something from media that isn't in the dictionary. When you click the link button there is no way to unlink a word, which is very annoying. It even changes the words you wrote if it thinks it's a different word. There needs to be a way to make it not link words that aren't in the dictionary and make it not change the words you write because otherwise it is unusable
The auto-parser is the same one as Text Analyzer, and it can only parse things that are in the dictionary. You'll have to use the normal parser to do anything that the parser cannot accept.
I'm actually not sure if the () is in the instructions, but
私 は (CrazyKanjiCompound) です。
Will force it to search for the word as an entire term, and refuse any attempts to break it up.
