Does anyone know of an Android plugin that can count Chinese characters?

Hello everyone, sorry to bother you. I don't know English, so this was translated using AI. I was wondering if there is an Android extension/plugin that can count Chinese characters? Although the Extra editor settings by Henry Heino has many great features that I really enjoy, the "Show word count" feature can only count English words, not Chinese characters. Also, the "Highlight spaces" feature doesn't highlight full-width spaces, like " ".

Characters or words?

Each character should be a single utf character, same as in latin.
