}
```

then...
My Chinese String has be translate to unicode...

I don't want to translate it...
help me...

Start with the gulpfiles.js snippet and the Babel configuration using the @babel/env preset. Reproduce the pipeline with the Chinese string, then determine whether the issue is in gulp-babel or Babel itself; done means the expected Chinese text is preserved in the generated output.

Written by the indexing model from the issue text.
