我用qwenimage生图，只要提示词里面有中文就会出现黑图

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

如果是纯英文提示词，就不会出现黑图，距举例，A girl is holding a sign in her hand, which reads "你好".这样的提示词就会出现黑图，黑图是在渲染的最后几步出现的，前几步的渲染都是正常的，最会几步会变黑

### Actual Behavior

如图

### Steps to Reproduce
