#3438

[chaojian-zhang]

Hi I am using Avalonia 0.9.4 with .Net Core 3.1, I am experiencing issue displaying Chinese characters:

1. I have tried all fonts that's mentioned including ones specifically for Chinese (e.g. 楷体) and it always displays a boxes (see screenshot) - however it's perfectly safe to copy those boxes from the application to other places and it will display correctly (e.g. inside Notepad++) so the encoding is right but somehow either the font is not working or the framework isn't loading the font correctly.
2. The letters display fine in title

I have looked into #3438 and that doesn't work as well.

Hi @chaojian-zhang, when you said "I have looked into #3438 and that doesn't work as well" - how have you tested it? That PR isn't part of an official release yet so you'll have to use our unstable packages: http://avaloniaui.net/docs/quickstart/packages#unstable-releases

[chaojian-zhang]

I saw on the issue page it's merged and thought that's already published.

I used Version 0.9.4 which was published on Wednesday, March 11, 2020 (3/11/2020). I am not sure whether that's the nightly build you were referring to though.

TextBlock can be displayed, but the TextBox also cannot display Chinese normally.

Setting TextBox FontFamily like this maybe useful for Chinese ：
"Microsoft YaHei,Simsun,苹方-简,宋体-简"

我这里直接设置系统字体可以解决，将 FontFamily 设置为 "Microsoft YaHei,Simsun,苹方-简,宋体-简"。
