[tex4ht] font choice in OpenOffice

[Thierry Masson]

Hello

I am new to tex4ht and I have to convert a pdflatex document to OpenOffice.
Using the command "mk4ht oolatex myfile.tex" I get a correct odt file.
The problem is that whatever font I install in the latex file, the text in the OpenOffice file is composed in "Liberation Serif".
How can I change this default behaviour?
I have tried using lualatex, but this does not solve my problem.

Thanks in advance
Thierry
