# Another question about making the name of an author bold in the bibliography [duplicate]

I'm using biblatex and wish to print a name (which has a "ä" character, say "Därwin") bold every time it shows up in the bibliography.

This answer provides a solution that works, provided my tex file is ISO-8859 encoded (I'm not sure I understand all the details about encoding). However, it ruins the detection of the last author in the list, whose name should be preceded by "and" and not followed by a comma. So instead of "Smith and Doe (1990)" I get "Smith, Doe, (1990)", even when the author printed in bold is Därwin.

Here's a MWE:

 \documentclass{article}
\usepackage[latin9]{inputenc}

\usepackage[style=authoryear-comp,natbib=true,%

\begin{document}

Les \oe{}uvres de \citeauthor{Darwin.84} ont souvent été citées, par exemple par \citet{Davies.pnas04,Vamosi.el10}.

\printbibliography

It produces this output:

How to get "and Savolainen, V. (2004)" ?
