[features required] Full OverLeaf fontsets support required

[itdevwu]

OverLeaf supports a lot of fonts which are listed in "Which OTF or TTF fonts are supported via fontspec?".

For CJK languages, especially Chinese, the default fontset provided by CTeX is fandol, whick is lack of many characters and isn't equipped with GSUB table, leading to missing or errors during rendering.

Google Noto is a project includes most characters on earth and is supported by OverLeaf officially in the previous link. In Chinese, it represents Source Han(Noto CJK). Thus, in most cases, supporting Noto is essential for CJK writers.

You can obtain its font file from Google Noto Fonts.

There're 2 steps to be done:

• Support Noto CJK,
• Support are Chinese fonts listed above.
