Japanese font rendering issue

[christophe-f8]

Wire version: 3.2.2860
Wire for web version: 2017.07.16.1405
Operating system: Windows 10

The rendering of Japanese is bad. The Kanjis (and only the kanjis) look wrong (not antialiased, it even looks like it's not the same font).
To sum up:

• alphabet and numbers: OK
• hiragana and katakana: OK
• kanjis: Bad rendering / wrong font

If you want to see the problem by yourself but not have any way to input Japanese, just paste this text:
abcd 1234 ひらがな　カタカナ　漢字
You will see that the rendering of the 2 last characters is bad.

This is quite annoying. For example, try to copy paste the following sentence (from a news website):
水温３５度「のぼせる」　夏休みのプール、開放中止相次ぐ

I think the problem can be solved by allowing the user to customize the fonts, or by selecting a font that has all characters in it (if a font that doesn't contain all characters is used, when a character not present in the font has to be rendered to OS will use another default font, so the characters won't match)

FYI, the new Skype client (also based on Electron if I'm not mistaken) also had this problem few months ago, but MS managed to fix it. As our organization is trying to leave Skype to use Wire we ope the issue can be solved quickly (PS: we can run tests if the need arises)

On Windows 10 Chrome 74 the characters look like this:

And look the same in Wire Desktop 3.9:

Is that what you mean?

Yeah, the rendering is wrong. It almost looks like it uses two different fonts (or maybe, some of the text is rendered with cleartype or some kind of filtering, and the rest is not) Just so you know, I think this is an Electron issue, since other electron apps have the exact same bug (Skype, ...) In the end I really couldn't bare with such text, so I switched to Zoom. Sorry...

This was fixed in electron/electron#15486 and should already be applied in Wire for Desktop 3.12. Can you check if it was fixed for you @christophe-f8?
