    • Subcomponent:
      2d
    • OS:
      os_x

      Description

      FULL PRODUCT VERSION :
      1.7.0_45
      1.8.0-ea-b121
      1.7.0_60-ea-b02

      ADDITIONAL OS VERSION INFORMATION :
      ProductName: Mac OS X, ProductVersion: 10.9.1, BuildVersion: 13B42

      A DESCRIPTION OF THE PROBLEM :
      Rendering diacritic characters in Thai texts does not work in DIALOG-Font, SANS_SERIF-Font and several other fonts, when running on OS X 10.9.
       

      ADDITIONAL REGRESSION INFORMATION:
      Works on OS X 10.8.5 (Mountain Lion) with same JVM


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      create a Java application with a TextArea or TextField and paste a Thai text into the field.
      You can use the URL "http://translate.google.com/#auto/th/ABCD%20you%20are%20the%20greatest" for this.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Should render correct diacritic characters
      ACTUAL -
      Diacritic characters are rendered as separate character.

      REPRODUCIBILITY :
      This bug can be reproduced always.
