As the title suggests, when loading Korean text, TTS only displays Chinese. I need Korean voice output. The file format is txt. It works normally when you load an epub. It seems that this issue only occurs when the format is txt. <img width="973" height="828" alt="Image" src="https://github.com/user-attachments/assets/286105df-ba15-4ddf-825a-9907157aca9a" />
