You need to download a special input method. I remember that there is an input method that can solve the problem. Because Romance of the Three Kingdoms is a game developed in Japan and translated into Chinese by Taiwan, so the general input method does not recognize it and it will not work. It's gibberish, the name of that input method: Game Pinyin Input Method. You can try this. But if your game is a Traditional Chinese version, then there is no input method, and you can only use a modifier to modify the name outside.
