Table and Figure caption not showing Bengali characters

[raheems]

I am testing the bookdown-demo-master to see if Bengali books can be written with bookdown. One issue I see is the caption of Tables and Figures. Non-English characters do not show up in the produced html file.

{r nice-tab, tidy=FALSE} knitr::kable( head(iris, 20), caption = 'The বাংলায় ক্যাপশন হচ্ছে কিনা পরীক্ষা করছি!', booktabs = TRUE )

When I run this, the output only shows "The !" in the caption of the table. That is it ignores the Bengali text completely. This is happening with Figure captions as well. Is there anything that I need to change to fix this? Thank you.

You are using Windows with an English locale. For best support of Bengali, you probably need to change your system locale to Bengali (from the Control Panel).

Thanks for the tip. I would believe this would solve the issue. Unfortunately, Bengali is not there under the Language for non-Unicode programs.

Then I'm afraid I cannot help. Sorry.

Totally understand. Thank you so much. For now I have to resort to LaTeX + Sweave for my upcoming project until that time when it will be easily accessible to other languages.
