Polyglossia error with htlatex for Kannada language

[diwakarshastri]

Hello,
I am trying to use tex4ebook for Kannada book. I am getting the following error. I have tried on Windows with Miktex and on Ubuntu with TexLive. Initially, I got a similar error in windows, but for some unknown reason, I am getting a different error.
Example.zip

I have attached the .tex and the screenshot of the error.

I used the tex4ebook -x kannada.tex command to convert the .tex to ebook format. I have also attached font Tunga.ttf which I have used in the document.

I don't know why this does not work with tex4ht (might be a problem or limitation of tex4ht), but it seems to help to add the following line:

\newfontfamily\kannadafont[Script=Kannada]{Tunga}

At least compilation succeeds then.

As to the problem I suggest you file a report at tex4ht's tracker:
https://puszcza.gnu.org.ua/bugs/?group=tex4ht

It seems that the Script option in \setmainfont is not yet supported in tex4ht (at least the examples given by the package maintainer suggest that)

@michal-h21 is the assumption correct that tex4ht currently does not consider the Script option of polyglossia's \setmainlanguage/\setdefaultlanguage and \setotherlanguage but rather requires fontspec's \newfontfamily\<script>font?

If so, is this worth a feature request at the tex4ht tracker?

[michal-h21]

@jspitz you are right, the script option didn't have an effect. I've just added the support to TeX4ht sources, so it should work after TL update.

[jspitz]

Cool, thanks @michal-h21.

@michal-h21 and @jspitz Thank you for the update. Although now the book is compiling, I am still getting the same error at places where I have used tables.

@diwakarshastri please report this to the tex4ht tracker.

@jspitz Ok thank you
