Ah, I didn't see that. However, if I recall correctly, the long-term plan is
to introduce a separate type for binary files. I would expect that the
caller has to explicitly specify an encoding when writing a String to such a
binary file. However, there still might be uses of text file handles with a
'char8' encoding. Hence, in the long-term, we can actually avoid confusion
by not choosing 'binary' as the name of this encoding.
