torch.load default encoding change to 'utf-8' (#26421)
Summary:
Default encoding when using torch.load to 'utf-8'
This commit provides changes for cases where user tries to torch.load
a pickled module with non-ASCII characters in the docstring as
discussed in https://github.com/pytorch/pytorch/issues/21743. The default encoding was changed from 'ascii'
to 'utf-8'. Documentation for `torch.load` was updated and two tests
(loading py2 unicode module with unicode in it; error throwing when
user explicitly sets wrong encoding) were written.
~~This commit provides changes for better error handling in cases
where user tries to `torch.load` a pickled module with non-ASCII
characters in the docstring as discussed in https://github.com/pytorch/pytorch/issues/21743.~~
