Solve coding problems outside English

[yibo7]

In the old version, I solved the problem of garbled code like this：

C#:

public static string ToString(byte[] data)
        {
            //return Encoding.UTF8.GetString(data);
            return Encoding.Default.GetString(data);
        }

js:

AlphaTab.Platform.Std.ToString = function (data){
    //... old code
    var s = new TextDecoder('gbk').decode(data);      
    return s;
};

How to solve it in the new version

You can control the encoding via importer.encoding setting.

What file formats are you using? Do you have an example file showing the issue?

[yibo7]

The files I use are. GP3,. Gp4. They can be encoded correctly in HTML, but they can't be encoded correctly in c# Chinese

This is one of my test files

I had a closer look and the issue seems to come from the fact that the default fonts used in alphaTab do not have chinese characters in it.
You will need to reconfigure alphaTab to use a font which has chinese characters in it using the resources option. The fonts need to be installed in the system because there is no public way to register custom font files (yet). You could by pass this with reflection by calling this internal method:

alphaTab/src.csharp/AlphaTab/Platform/CSharp/SkiaCanvas.cs

Line 68 in 70eb7c3

public static void RegisterCustomFont(byte[] data)

I gave it a test to change the title font to "SimSum" (default Windows font for Chinese characters) and it displays the characters correctly:

settings.Display.Resources.TitleFont = new Font("SimSun",
    settings.Display.Resources.TitleFont.Size,
    settings.Display.Resources.TitleFont.Style,
    settings.Display.Resources.TitleFont.Weight);

It seems browsers have some advanced fallback mechanism to change the font on character level.
