Problem Description

In current Chromium font fallback implementation, the prioritized font for Simplified Chinese and Traditional Chinese are set to SimSun and PMingLiu on purpose, which is very inconsistent with most western typefaces.

Proposed Solution

Prioritize “Microsoft YaHei” and “Microsoft JhengHei” instead.

Alternatives Considered

A better solution may be defining multiple font fallback sequences for different font styles: one for serif, one for sans-serif, and have different priority for specific fonts.

I was hoping you'd also fill out the part of the template that specifies the Electron version that you saw this issue in, as we've changed some font fallback things in recent versions.

In general we tend to follow Chrome's behaviour as closely as we can. For instance, #15486 changed Electron's fallback fonts to match Chrome's. If you believe that this is not the optimal fallback font behaviour for Chrome, consider filing a bug against Chrome at https://crbug.com/new.

@nornagon Considering that this issue is sent by people from Microsoft (as what you may already know) who is working on the CJK font experience of Windows, I suggest you to treat Believe's opinion prior to the official default behavior of Google Chromium. If the source code of Edge Chromium is available, its behavior (which is optimized by Microsoft) can be your new reference.
