        Description

        When I used Surrogate Pair character on JTextField on macOS, unexpected symbol (square) was displayed at the end of line.

        I used following build.
        $ ~/jdk-16.jdk/Contents/Home/bin/java -version
        openjdk version "16-ea" 2021-03-16
        OpenJDK Runtime Environment (build 16-ea+24-1553)
        OpenJDK 64-Bit Server VM (build 16-ea+24-1553, mixed mode, sharing)

        Please see attached screen shot and testcase.

        According to my investigation, I could recreate this issue after JDK13.
        I could not recreate this issue on JDK 12.0.1, but I could recreate it on JDK 12.0.2.
        I assume this issue came from HarfBuzz upgrade (JDK-8220392)

        Base update might be JDK-8210782.
        In these days, HarfBuzz was upgrade by JDK-8247872, it should be in 16-b24.
