Is there a simple way to wrap a built-in function for the whole package?

I like to redefine all the open() there with the default encoding 'utf-8', but not for code outside the package. Maybe I can put my def statement at the beginning of every module of this package, but just wondering is there a simple way of doing it?

Instead of changing open() to open8() throughout the code, I prefer change it  directly to open(encoding='utf-8'). Anyway, using "from . import open" is a good idea, thank you.
