Follow-up Comment #2, bug #475 (project tex4ht): Hello Diwakar,
I don't get any error with your file. Do you use up-to date TeX Live? I've fixed some Polyglossia issues in May (it was exactly the error you linked to in your question). You don't need to require tex4ht and tex4ebook packages in your document, they are loaded automatically by TeX4ebook command. You would need to use tex4ebook package only if you wanted to use the \coverimage command in your document. You can put all tex4ht configurations to a configuration file and pass it to TeX4ebook using the -c option. For example, the cover image can be declared using \CoverMetadata{imagename.png} in the .cfg file. The configuration file may look like this (change the values according to your needs): \Preamble{xhtml} \Configure{DocumentLanguage}{KN} \CoverMetadata{mycover.png} \Configure{UniqueIdentifier}{https://your.website.url} \begin{document} \EndPreamble Best regards, Michal _______________________________________________________ Reply to this item at: <http://puszcza.gnu.org.ua/bugs/?475> _______________________________________________ Message sent via/by Puszcza http://puszcza.gnu.org.ua/
