Follow-up Comment #1, bug #626 (project tex4ht): Thanks for the report and the provided fix. I was able to reproduce this issue if I used the Babel package multiple times in the document.
Actually, you don't need to use \RenewDocumentCommand\:babelfont, the \ProvideDocumentCommand version suffices. I've uploaded the fix to TeX4ht sources. _______________________________________________________ Reply to this item at: <http://puszcza.gnu.org.ua/bugs/?626> _______________________________________________ Message sent via/by Puszcza http://puszcza.gnu.org.ua/
