            Bug ID: 140252
           Summary: REGRESSION(r177637) [HarfBuzz] [GTK] [EFL] Missing
                    glyph symbols are not rendered.
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

After r177637 <https://trac.webkit.org/r177637> and r177876 <https://trac.webkit.org/r177637> the missing glyph symbols are not rendered.

On bug 139905 a crash caused by r177637 was fixed on r178115 <http://trac.webkit.org/r178115> but that was an incomplete fix, because looking at the results of the tests the missing glyph symbol (the square) is now gone. http://people.igalia.com/clopez/bug-139905-results-img/results.html

On the GTK port, at least the following tests are affected:

Regressions: Unexpected text-only failures (15)
  fast/css/line-height-determined-by-primary-font.html [ Failure ]
  fast/ruby/bopomofo-letter-spacing.html [ Failure ]
