Fail to sort nomenclature using prefix

Question

I'm trying to get my nomenclature to sort alphabetically, including word with accent. Basics! Well, I read all \nomencl documentation and many of your expert answers here... So I tried different things, inserted a prefix and modified my build.bat to run LaTeX, makeindex <filename>.nlo -s nomencl.ist -o <filename>.els, rerun LaTeX, then pdflatex...

\documentclass[11pt,a4paper,twoside]{book}

\usepackage[T1]{fontenc}
\usepackage[ansinew]{inputenc}
\usepackage{lmodern}
\usepackage{titletoc}
\usepackage{tocloft}
\usepackage{nomencl}
\usepackage{makeidx}
\usepackage[frenchb]{babel}

\makenomenclature

\begin{document}

\printnomenclature[7em]

\nomenclature{déc.}{Décision}
\nomenclature[e]{éd.}{édition}
\nomenclature{Gaz. Pal.}{Gazette du palais}

\end{document}

For some reason, it's still not working for me... I'm close to take it personally!

Answer 1

There is a default prefix a that is added before the entries without optional argument. Therefore aGaz... is sorted before e.... You can redefine the default prefix to an empty string:

\renewcommand*{\nomprefix}{}
