  • How to reproduce

  1. Grab NotoSansKR-Regular.otf [1] from the AOSP ( git clone https://android.googlesource.com/platform/external/noto-fonts ). The AOSP has 1.001. What I tried is 1.002 and 1.004.

  2. Strip CFF hints using '--no-hinting' option to pyftsubset without '--desubroutinize'.

  3. Run the following

    $ ftview -m '알림 삼진 원섭' 16 NotoSansKR-Regular.otf
    $ ftdiff -f krtext NotoSansKR-Regular.otf
    where 'krtext' file has '알림 삼진 원섭'

    $ hb-view --output-file=krtest.png NotoSansKR-Regular.otf "알림 삼진 원섭"

    • FT 2.5.5 + Noto Sans KR 1.001 : The positions of '림' and '섭' are incorrect
    • FT 2.5.5 + Noto Sans KR 1.002 : The positions of '림', '진' and '섭' are incorrect.
    • FT 2.6/ToT + Noto Sans KR 1.002 : The positions of '림' is incorrect while '진' and '섭' are correct.

Below is the image taken with FT 2.5.5 + Noto Sans KR 1.002

[1] This is an Android-specific fallback version and is different from what's available from googlei18n/noto-cjk
