Couldn't Subversion automatically convert UTF-16 files to UTF-8 before
processing them for diff/merge/blame, and convert output written to
the original files back to UTF-16?
That would require some work because existing streams, strings, and files
passed around in the code would need to be wrapped so that translation
to/from the internal from/to the external encoding is seamless.
But I don't see why such an approach couldn't be made to work in principle.
It might even result in some spring cleaning in the code base and pave the
way for improved handling of file formats such as XML for diff and merge.
What do you think? Is it worth adding this to our project ideas page?
