Unicode text issue with html sub pages in cordova

Question

I need to show marathi text in html page, so I have set charset="UTF-8" in the index.html page in meta tag. So when I past marathi text directly in html " <div class="title">???? ?????? ???? ????</div>" then it's showing fine. but there is an issue with sub pages.

 

I am currently working with Framework7. Here, Index.html is my main page and about.html is a sub page which open though routes.

 

Marathi text is showing fine which are in index.html page, but when an open sub page "about.html" then showing ?????? ??. It's means charset="utf-8" is not effected on sub pages.

 

Here, if I manage marathi font then it will be a big task to handle, so anybody know a solution?
