Steps to reproduce the problem:
1. Create a new profile to avoid other factors.
2. Change your interface language to Simplified Chinese.
3. Restart Chrome.
4. Open https://en.wikipedia.org

What is the expected behavior?
Content should be shown in English fonts, such as Arial.

What went wrong?
When using non-English interfaces, such as Japanese or Chinese, the default internal settings for Latin script is set to "use default fonts", which are Japanese/Chinese fonts (MS PGothic and SimSun, to be more specific). 

This is sub-optimal because these fonts are not designed for Latin scripts. It looks ugly (see repro and the screenshots provided).

It should explicitly use Latin scripts such as Arial, Times new Roman, for Latin script content in these locales' default settings.

It is *already* the practice for some other situations: 

When you're on English interface,  and visiting Chinese/Japanese content, it will use Chinese/Japanese fonts, respectively;
When you're on Chinese interface, and visiting Japanese content, it will use Japanese fonts (instead of your default chinese fonts).

This issue is to propose:

When you're on Chinese interface, and visiting English content, it SHOULD use English fonts (instead of your default chinese fonts).

Did this work before? No
