WebView displays garbled character on some websites.

    Details

    • Subcomponent:
      web
    • CPU:
      x86
    • OS:
      os_x

      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_121"
      Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
      Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      macOS Siera ver 10.12.1 (16B2555)

      A DESCRIPTION OF THE PROBLEM :
      Some websites such as blogs from http://www.wordpress.com will attempt to render web page, but many of the characters aren't readable. I believe the webkit crashes and doesn't finish rendering html.

      Go to any blog from wordpress such as mine below:
      https://carlfx.wordpress.com

      When rendered in any browser the html renders fine.


      REGRESSION. Last worked in version 8u112

      ADDITIONAL REGRESSION INFORMATION:
      This can be reproduced in update 112 also.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Create a JavaFX application with a WebView control to load a WordPress blog such as http://fxexperience.com or http://carlfx.wordpress.com

      I've attached code to test this issue.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The WordPress blog website's html pages render incorrectly and the text is readable.
      ACTUAL -
      The WebKit crashes, and the html page renders incorrectly and the text is unreadable.
