Old Hangul in vertical writing renders problematically #107

Closed guocuozuoduo closed 7 years ago

guocuozuoduo commented 7 years ago

In both Word 2016 and LibreOffice Writer 5.4.1.2, old hangul written horizontally appears normal: image image While in both programs, the same text written vertically appears problematic (note that Noto Sans CJK KR Regular appears normal in Word, but Noto Serif CJK KR appears problematic, while both fonts appear problematic in LibreOffice): image image Fonts tested were Noto Sans CJK KR Regular and Noto Serif CJK KR, using the characters ᅚᆘᆹꥹힾퟠᅇᅡᇮ.

First of all, neither MS Word nor LibreOffice Writer are considered good examples of combining jamo, especially for vertical writing mode.

We eventually determined that the ideal long-term way to support vertical combining jamo is via the 'vert' GPOS (not GSUB) feature. For the short term, some environments will not support this, which we understand. The latest Noto Serif CJK (and Source Han Serif) supports this feature, while the latest Noto Sans CJK (Source Han Sans) does not, but will in the next release.

Although not likely to work, can you try Noto Serif CJK and see how it works in MS Word and Libre Office ? @guocuozuoduo

@jungshik Noto Serif CJK has the same problem, and LibreOffice doesn’t even recognize them as separate fonts (I.e. whether the font is SC, TC, JP or KR has no effect on the style of CJK characters, it is the language that determines that).
