Chinese characters disappearing after export to PDF

[JustArthur]

I am working on a document with Chinese characters, but they disappear after I export to PDF.

I created a test document and try to reproduce the problem, and it might be specific to NotoSansHK.

In Affinity Publisher, I have the Chinese characters in Grandstander (which doesn't have support for Chinese characters, hence the preflight warnings), in NotoSansHK (Google Font with Open Font License) and in DFKai-SB (a font that comes with Windows).

Despite failing the preflight, the Chinese characters in Grandstander show up fine in the PDF. The Chinese characters in NotoSansHK however becomes white space. DFKai-SB is also exporting fine.

I use Google Font a lot because of the Open Font License. I am confused about the license for fonts that come with Windows, so I don't use them for commercial work.

I guess I want to understand what the problem is, and if there is a way to fix it. (It is also annoying to find out some of my chosen fonts wouldn't show until I export them to PDF, as I have already done the layout around them. If I understand what makes some fonts problematic, I can avoid working with them in the future.)

猜测是字库不包含中文字体，选择中文字体，更改字体为思源黑体等中文字库试一试呢。🥰

問題出於 Noto Sans Hong Kong (https://fonts.google.com/noto/specimen/Noto+Sans+HK)

根據維基百科 (https://zh.wikipedia.org/wiki/思源黑體)，Noto Sans 就是思源黑體？

我剛下載了NotoSansTC(https://fonts.google.com/noto/specimen/Noto+Sans+TC), 似乎沒有問題。

是的我刚要回复你，NoteSansHK内不包含那几个字，只需要换其他思源黑体就可以解决。
