You raise a good point.
There is a problem with binutils paths generally.
POSIX path names are constrained to a fairly small set of characters.

In Windows land unicode characters are allowed.

However, I do not think PR 25713 is going to tackle that larger issue.
I think it should be restricted to dealing with the filename as provided by the
first argument to _bfd_real_fopen. 
https://github.com/bminor/binutils-gdb/blob/fb583cfc0936554a1f8d86ef2b6649bf511d6df8/bfd/bfdio.c#L89

    FILE *_bfd_real_fopen (const char *filename, const char *modes);

Is there any plan to tackle the issue of accommodating paths from multiple
filesystems?
