Default Font should support Unicode 10

Reported by taub...@gmail.com, Oct 26 2017

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Example URL:
https://got.wikipedia.org/

Steps to reproduce the problem:
1. Visit a site using Unicode 10 such as gothic wikipedia
2. See that the unicode is not included in the default font

As a note, if you highlight the text and then right-click you will have the option to copy or search for the term and it's correctly rendered

What is the expected behavior?
Chrome properly renders Unicode 10 characters using the default font

What went wrong?
Font doesn't support Unicode 10

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? No 

Does this work in other browsers? Yes

Chrome version: 61.0.3163.100  Channel: stable
OS Version: OS X 10.12.6
Flash Version: 

Thanks for all the hard work you do!

Able to reproduce the issue on Mac OS 10.12.6 using chrome M62 #62.0.3202.75 and M64 #64.0.3253.0 .

This issue seen from M50 and is a Non-Regression Issue and the behavior is different in windows 10 and ubuntu 14.04.

Marking it as untraiged for further inputs in this.

Thanks!

Over to the Mac team for further triage. Changing the default would be pretty easy, it's finding the right default that is tricky.

There are instructions - https://got.wikipedia.org/wiki/%F0%90%8C%B7%F0%90%8C%B9%F0%90%8C%BB%F0%90%8D%80%F0%90%8C%B0:How_to_enable_the_Gothic_font they worked for me :). But Safari doesn't need that.

The site uses the following font fallback list - 'Linux Libertine','Georgia','Times',serif

But even changing that to include or use BlinkMacSystemFont explicitly fails to find the glyphs. (disclaimer: I don't really know how BlinkMacSystemFont works.. or css for that matter :) )

I think this is a font fallback issue in Blink, and someone familiar with that should take a look. I haven't had a dive in to that side of fonts yet.

The font displays correctly when using gfx::RenderTextHarfBuzz and the font fallback mechanism in ui/gfx/font_fallback_mac.mm
