Unversioned files with invalid UTF-8 sequence in name confuse svn

With:

svn, version 1.9.3 (r1718519)
   compiled Jan 16 2016, 04:46:46 on x86_64-pc-linux-gnu

I have a working copy where "make check" has created files whose
name contain invalid UTF-8 sequences. The consequence is that
such files confuse svn:

$ =svn st
svn: E000022: Error converting entry in directory '/home/vlefevre/software/mpfr-3.1/tests' to UTF-8
svn: E000022: Valid UTF-8 data
(hex: 04 10 40 04 04 04 02 01 46 04 40)
followed by invalid UTF-8 sequence
(hex: c0 2e 69 64)
zsh: exit 1 =svn st

I think that a fatal error is a bug, i.e. "svn st" should just report
that these files are unversioned. The requirement on the validity of
filenames should just apply to versioned files or files to be versioned.

These files can't even be removed with svn-clean, which reports the
same error.
