babel: Mixing English and Chinese Using Google NotoFonts

Question

Goal

My goal is to have a document that contains two languages, English and (simplified) Chinese.
Both languages will appear in an equal amount (one paragraph English and then one paragraph Chinese).
I compile with LuaLaTeX using TeXLive.
I want to use the Noto font that is provided by Google.
Later I want to use a KOMA document class (and not a Chinese-specific document class).

MWE

\documentclass{article}

\usepackage[english]{babel}
% babelprovide for *english* (default language of the document)
\babelprovide[
    main,
    import,
    language = Default]
    {english}

% babelprovide for *chinese-simplified*
\babelprovide[
    import,
    language = Chinese Simplified]
    {chinese-simplified}

%% Choose actual fonts for different font variants.
% Font for font variant "rm" (Serif)
\babelfont{rm}{Noto Serif}
% Font for font variant "sf" (Sans Serif --> Without Serif)
\babelfont{sf}{Noto Sans}
% Font for font variant "chinese-simplified"
\babelfont[chinese-simplified]{rm}{Noto Serif CJK SC}

TeXLive Font Status

I have several Noto font folders in my TeXLive installation. I assume that the opentype folders are used when I use LuaLaTeX.

Question / Problem

Is my code correct / best practice for the intended purpose?
I do not get bold Chinese characters, although they seem to me available.
Strangely, even the bullet points of itemize changed in the Chinese part.
When I add \babelfont[chinese-simplified]{sf}{Noto Sans CJK SC} (Sans Serif Chinese Font) then I get an error: ! Package fontspec Error: The font "NotoSansCJKSC" cannot be found.. I do not understand why (NotoSansCJKsc-Regular.otf is in the same font folder as NotoSerifCJKsc-Regular.otf.).

Update

User David Purton proposed the following font setup:

\babelfont{rm}{Noto Serif} 
\babelfont{sf}{Noto Sans} 
\babelfont{tt}{Noto Sans Mono} 
\babelfont[chinese-simplified]{rm}{Noto Serif CJK SC} 
\babelfont[chinese-simplified]{sf}{Noto Sans CJK SC} 
\babelfont[chinese-simplified]{tt}{Noto Sans Mono CJK SC}

You could try specifying the actual font file names instead of its family name. — David Purton, Dec 28 '19 at 13:23
@DavidPurton Thanks! Can you show your complete code (in an answer, incl. tt and sf, I will upvote) so that I am sure that there is no misunderstanding? — Dr. Manuel Kuehner, Dec 28 '19 at 13:49
My code is exactly the same as yours. The full font set up is: \babelfont{rm}{Noto Serif} \babelfont{sf}{Noto Sans} \babelfont{tt}{Noto Sans Mono} \babelfont[chinese-simplified]{rm}{Noto Serif CJK SC} \babelfont[chinese-simplified]{sf}{Noto Sans CJK SC} \babelfont[chinese-simplified]{tt}{Noto Sans Mono CJK SC} — David Purton, Dec 28 '19 at 13:50
@DavidPurton Thanks. How do you install the fonts, on the TeXLive tree or as system fonts? And about You could try specifying the actual font file names instead of its family name., how do I do that since there are so many files (bold and so on). — Dr. Manuel Kuehner, Dec 28 '19 at 13:53
@DavidPurton I get several ! Package fontspec Error: The font "NotoSansCJKSC" cannot be found. when I use your font setup. — Dr. Manuel Kuehner, Dec 28 '19 at 13:55
@DavidPurton Can I see somehow in the log file which font fiel is actually used? — Dr. Manuel Kuehner, Dec 28 '19 at 13:57
See "§2.2 By File Name" in the fontspec manual to load fonts with more precision than you get by just giving the family (in this case fontspec guesses a lot). The syntax is \babelfont[babel settings]{family}[fontspec settings]{base font file name} — David Purton, Dec 28 '19 at 14:00
LuaLaTeX outputs which fonts are used to the console. For me it is a mix of system fonts and fonts in the TeX tree. — David Purton, Dec 28 '19 at 14:01
@DavidPurton Thanks. Are you willing to generate an answer incl. the proposal? — Dr. Manuel Kuehner, Dec 28 '19 at 14:01

From comments, it turns out that you copied the CJK fonts into your main TeXLive tree. TeX can't find them unless they are indexed though.

You can either load the fonts by filename (see below), or install the fonts in your local texmf tree.

You can find this by running:

kpsewhich -var-value=TEXMFHOME

The fonts should likely go in

$TEXMFHOME/fonts/opentype/google/notocjksc/

TeX can find these automatically. You can confirm this by running

`kpsewhich NotoSansCJKsc-Regular.otf`

and the font full path should be returned.

For loading the fonts by file name, you can use:

\babelfont[chinese-simplified]{rm}[
  Path = C:/texlive/2019/texmf-dist/fonts/opentype/google/notocjksc/ ,
  Extension = .otf ,
  UprightFont = *-Regular ,
  BoldFont = *-Bold ,
  ItalicFont = *-Regular ,
  BoldItalicFont = *-Bold]{NotoSerifCJKsc}

\babelfont[chinese-simplified]{sf}[
  Path = C:/texlive/2019/texmf-dist/fonts/opentype/google/notocjksc/ ,
  Extension = .otf ,
  UprightFont = *-Regular ,
  BoldFont = *-Bold ,
  ItalicFont = *-Regular ,
  BoldItalicFont = *-Bold]{NotoSansCJKsc}

\babelfont[chinese-simplified]{tt}[
  Path = C:/texlive/2019/texmf-dist/fonts/opentype/google/notocjksc/ ,
  Extension = .otf ,
  UprightFont = *-Regular ,
  BoldFont = *-Bold ,
  ItalicFont = *-Regular ,
  BoldItalicFont = *-Bold]{NotoSansMonoCJKsc}

Seems to work! Thanks. – Dr. Manuel Kuehner Dec 28 '19 at 14:23
It's meant to be faster to load by file name under LuaTeX as well. – David Purton Dec 28 '19 at 14:26
I forgot to mention in my question, that I installed the notocjksc fonts manually from CTAN. – Dr. Manuel Kuehner Dec 28 '19 at 14:31
@Dr.ManuelKuehner Ooooh! Did you run mktexlsr so that TeX knows about the files? Does kpsewhich NotoSansCJKsc-Regular.otf return anything? What about kpsewhich NotoSerifCJKsc-Regular.otf? – David Purton Dec 28 '19 at 14:33
I think manually installed packages are not meant to go in the main TeX tree anyway. – David Purton Dec 28 '19 at 14:34
kpsewhich NotoSansCJKsc-Regular.otf does not return anything (also no error). Do you know where I should put the fonts? Since it partly worked so far, I had no reason to think that is is a mistake :) – Dr. Manuel Kuehner Dec 28 '19 at 14:40
I will be damned! I just tried mktexlsr on a console (cmd) with admin privileges and now it seems to work without specifying the font file and so on. I used the TeXLive GUI and updated everything I could find before. – Dr. Manuel Kuehner Dec 28 '19 at 14:44
I will upvote some of your other answers to thank you. – Dr. Manuel Kuehner Dec 28 '19 at 14:49
Thx for the update! – Dr. Manuel Kuehner Dec 31 '19 at 21:50
