Biber 1.9 --output_format=bibtex returning error

[bgouhier]

I am trying to convert a biblatex list of reference into a list of bibitems following these instructions:
http://tex.stackexchange.com/questions/154215/biblatex-biber-to-bibitem

It worked flawlessly until I updated biblatex to 2.9 via mixtex, and to biber 1.9. Now the command "biber --output_format=bibtex main" returns an error:
Undefined subroutine &Biber::Output::bibtex::NFC called at C:/.../inc/lib/Biber/Output/bibtex.pm line 129

Running the command with biber 1.8 works.

MWE:

\documentclass{article}
\usepackage[backend=biber,sorting=none]{biblatex}

\begin{filecontents}{references.bib}
@Article{citation1,
author = {Author1},
title = {Title1},
journal = {Journal1},
year = {2008},
volume = {26},
pages = {316-324},
number = {6}
}

@Article{citation2,
author = {Author2},
title = {Title2},
journal = {Journal2},
year = {2007},
volume = {46},
pages = {4589-4597},
number = {15}
}

@Article{citation3,
author = {Author3},
title = {Title3},
journal = {Journal3},
year = {2005},
volume = {280},
pages = {30392-30399},
number = {34}
}
\end{filecontents}

\addbibresource{references.bib}

\begin{document}
Citation 1: cite author2 \cite{citation2}

Citation 2: cite author3 \cite{citation3}

Citation 3: cite author1 \cite{citation1}

\printbibliography
%
\end{document}

Name this file main.tex and run the below script (Windows) which is a .bat file I wrote based on the previous link to create a dummy.bib with the list of refs in bibitems:

set LATEX_PATH=C:\Program Files\MiKTeX 2.9\miktex\bin\x64
set TEX_FILE_NAME=main

"%LATEX_PATH%\biber" --output_format=bibtex "%TEX_FILE_NAME%.bcf"
echo \documentclass{article} > dummy.tex
echo \begin{document} >> dummy.tex
echo \nocite{*} >> dummy.tex
echo \bibliography{%TEX_FILE_NAME%_biber} >> dummy.tex
echo \bibliographystyle{unsrt} >> dummy.tex
echo \end{document} >> dummy.tex
"%LATEX_PATH%\pdflatex" dummy
"%LATEX_PATH%\bibtex" dummy

Can you pull 1.9 from SourceForge? I have corrected this and updated the 1.9 build.

Yep its working now.

Thanks for the quick reply/fix !
