Semi.Avalonia does not support Vietnamese language?

[andreyk6617]

recently tried Semi.Avalonia for my application, my application supports multiple languages. However, for Vietnamese, the application shows an error that the characters "ố ă ă..." are smaller than other latin characters. This also happens when entering data into TextBox.... is there any way to fix this? It seems that the font is missing Vietnamese characters. This happens even on the demo application of Semi.Avalonia

This relates to font. Semi Avalonia is not tied to any specific font, You can change it to any font you need. Our demo is utilizing Microsoft YaHei, maybe that's why it looks ugly.

i tried google fonts, but the result is still the same. This only happens when using Semi.Avalonia

This is one of the apps we use Semi.Avalonia and Alibaba PuHuiTi, I think the Vietnamese characters looks fine?

I still don't understand the reason, reinstalling system locate on windows, installing full system font set. all doesn't work.

Hi, I don't mean you are reporting an invalid problem, I just don't know if the characters are displayed properly and ask for your advice.

There are two things you can do to override the default font resource in Semi.Avalonia.

1. override the default font family

Semi defined below default font fontfamily, you can redefine it in your resource dictionry with a font that display Vietnamese characters:

Semi.Avalonia/src/Semi.Avalonia/Tokens/Variables.axaml

Lines 64 to 68 in ffbd8ef

	<FontFamily x:Key="SemiFontFamilyRegular">
	Inter, -apple-system, BlinkMacSystemFont, PingFang SC,
	Microsoft YaHei, Segoe UI, Hiragino Sans GB, Helvetica Neue,
	Helvetica, Arial, sans-serif
	</FontFamily>

2. Set default fallback font in your application

We set Microsoft YaHei as our fallback font in demo app, you can choose another one.

Semi.Avalonia/demo/Semi.Avalonia.Demo.Desktop/Program.cs

Lines 15 to 24 in ffbd8ef

	.With(new FontManagerOptions
	{
	FontFallbacks =
	[
	new FontFallback
	{
	FontFamily = new FontFamily("Microsoft YaHei")
	}
	]
	})

setting DefaultFamilyName and FontFallbacks doesn't work. It only works when Semi.Avalonia is removed. I think it's Semi.Avalonia overriding the font settings.

Weird, I setup a demo, and several controls with Vietnamese characters, and it looks fine on my machine.
