The bbl file generated by biber (with LIBC_ALLOWCTYPEABUSE set)
is corrupted.

My .bib file is:

@book
{
        test ,
        author          = {Auteur Accentué} ,
        title           = {Titre accentué} ,
        subtitle        = {Sous-titre accentué} ,
        publisher       = {Éditeur} ,
}

I'm experiencing the crashes when using UTF-8 accented
characters.

The bbl file generated by biber contains:

      \name{author}{1}{}{%
        {{hash=91f7bdcdb5ba9aa364fc899a9b5ee245}{%
           family={Accentu�},
           familyi={A\bibinitperiod},
           given={Auteur},
           giveni={A\bibinitperiod}}}%
      }

The family value is not valid UTF-8, hence the problem.  On the
other hand, the values for all the other fields are valid UTF-8.

The problem is the same if I use old-style ASCII syntax for
accented characters:

        author          = {Auteur Accentu{\'e}} ,

So it looks like a biber (or some of its pkgsrc dependencies)
issue.

On Linux, everything processed from scratch is OK and I get the
same messages from LuaLaTeX when using the
print/p5-biblatex-biber+LIBC_ALLOWCTYPEABUSE'd file from NetBSD
11.0_RC1 because the problem is inside it.
