Regarding WORDSNET-17583, please run the following code on your machine and provide console output and resulting image.

using (Bitmap bmp = new Bitmap(1000, 100))
{
    using (Graphics gr = Graphics.FromImage(bmp))
    {
        Font fnt = new Font("DFKai-SB", 100, FontStyle.Regular);
        Console.WriteLine(fnt.FontFamily.Name);
        using (GraphicsPath path = new GraphicsPath())
        {
            path.AddString("環球旅行第五十五期", fnt.FontFamily, (int) FontStyle.Regular, 100, PointF.Empty, StringFormat.GenericTypographic);
            gr.FillPath(new SolidBrush(Color.Black), path);
        }
        bmp.Save("out.png");

@PowerHu,

Thanks for the details. We will keep you posted on any further updates.

@PowerHu,

It seems that we have identified the problem. Aspose.Words currently searches the font family by English name but on your machine, FontFamily.Name seems to be returning the localized name.

Please also run the following code and provide the console output.

Font fnt = new Font("DFKai-SB", 100, FontStyle.Regular);
Console.WriteLine(fnt.FontFamily.GetName(0));
Console.WriteLine(fnt.FontFamily.GetName(new CultureInfo("en-US").LCID));
16

The console output is as bellow.out.png (2.7 KB)

17

@PowerHu,

It seems that you have again attached the same out.png that you attached earlier in your this post.

Please execute the following code and provide the output shown in visual studio’s console.

Font fnt = new Font("DFKai-SB", 100, FontStyle.Regular);
Console.WriteLine(fnt.FontFamily.GetName(0));
Console.WriteLine(fnt.FontFamily.GetName(new CultureInfo("en-US").LCID));

I am sorry for upload the old output . I have upload the new output .outputex.png (460 Bytes)
