I have been using PDFTron third party Library which is used to Launch the .pdf/.doc/.xls/.ppt/.doc ....etc kind of documents pages on WKWebView.
on the WkWebview, document (eg: .pdf document) is loading and showing the pages like a book.
There is NO issue While adding Annotations on any page with "ENGLISH".
There is an issue that While adding Annotations on any page with Other Language letters like Tamil/China/Japan ...etc language letters then those letters converting as JUNK letters in the WKWebviewer. It seems to that WKWebviewer is not supporting unicode characters as an annotations. Please suggest for the Fix.
