Goal: To select useful fonts to be bundled with LO for use as default font for CJK document creation, providing open source fonts, as well as possibly providing a useful fallback font

Heading (YaHei), SimSun (Others)

1) Ship the regular (IPA Mincho, IPA Gothic) or proportional (IPA P Mincho, IPA P Gothic) IPA fonts rather than both versions. Which of the two versions are more used? I prefer the proportional one :D

2) Naruoga: what do you think of the Takao derived IPA fonts?

3) As we already ship Source Sans Pro, wouldnt it be possible to compile a version of Noto Sans without Latin glyphs which would be alot smaller?

4) Possibly only bundle Noto simplified chinese font to keep size down to a minimum

Thoughts from Cheng-Chia Tseng

0) If we want to make sure cross-platform consistence of default document creation (on Win, Linux and Mac), we should select open License CJK fonts for each locale to bundle with LibreOffice. If we want to make sure the interoperability with MS Office, we should just list Win fonts and ask Linux/Mac users to try their best to get Win fonts; however, I don't agree with this method as the goal of LibreOffice is NOT to serve as a "MS Office alternative".

1) There is NO one true CJK font solution for CJK environments. We should select suitable fonts for each CJK locale to serve them well, instead of trying to force them all using crappy fonts instead.

2) Conventional Chinese (including simplified and traditional Chinees) publications uses Hei (sans) or Kai (cursive) for Heading, Ming (serif) for Body text, Fangsong (fangsong) for emphasias (like Italic usage in Western languages. I stronly suggest at least pick one for Hei, one for Kai, one for Ming and one for Fangsong (not having open fonts for simplified Chinese yet) for Chinese locales to bundle with.

3) I suggest using Source Han Sans/Noto Sans CJK fonts for default CJK sans style fonts and Source Han Serif/Noto Serif CJK for default traditional Chinese ming/serif sytle font because they are Pan-CJK fonts which supports region-specific variants of Hanzi and having many font weights to create documents of good typography.

4) I suggest adding 全字庫正楷體 for default traditional Chinese cursive style font, and adding cwTeX Q FangSong for tradtional Chinese fangsong style font to bundle with.

Italics Usage (on telegram)

Vdragon: "Not that much I believe"

Cheng-Chia Tseng: "Seldom used in the publishing industry. (But used frequently by people who don't learn the typography and use word processing software directly."

DaeHyun Sung: "Also Korean is no italic fonts. This is because there is no italic font in Korean when typesetting English so they replace it with punctuation marks. Ref: http://koreantypography.org/blog/archives/tag/italic "
