[xindy] New hyperref specifications leads to "unknown cross-reference-class `hyperindexformat'!"

[Denis B. <dbi...@wa...>]

Hello,

in http://www.tug.org/applications/hyperref/ftp/ChangeLog, one can see
that, since version 6.79d, hyperref provides "full support of
makeindex's encap feature (e.g. \index{alpha|textbf}). \hyperpage and
the formatting command are cascaded via \hyperindexformat. Internally
\index{alpha|textbf} is transferred to
\index{alpha|hyperindexformat{\textbf}}..."

So, the minimal complete example test.tex file:

\documentclass[frenchb]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern, makeidx}
\usepackage{babel}
\usepackage{hyperref}
\makeindex
\begin{document}
foo\index{foo}
\newpage
bar\index{bar|see{foo}}
\printindex
\end{document}

leads, when processing through:

texindy -v -L french test.idx

to the following warning:

WARNING: unknown cross-reference-class `hyperindexformat'! (ignored)

Is there a workaround?

BTW, as I'm working in utf-8, I was surprised too see in texindy's
output:

Loading module "lang/french/latin9-lang.xdy"...
Loading module "lang/french/latin9.xdy"...
Finished loading module "lang/french/latin9.xdy".
Finished loading module "lang/french/latin9-lang.xdy".

And running:

texindy -v -C utf-8 -L french test.idx

leads to:

Cannot locate xindy module for language french in codepage utf-8.

Thanks!
