Loading a font with multiple files?

Question

It is possible to load a font from the LocalState directory:

textBlock.FontFamily = new FontFamily("ms-appdata:///Local/angsa.ttf#Angsana New");

But what if there are multiple files for the font:

angsa.ttf (normal)
angsai.ttf (italic)
angsab.ttf (bold)

The user should only see 'Angsana New' once in the font selection. If he chooses bold, italic or normal, does the programmer have to guess/know which font file to load?

Or is there a way to load all font files for the font with a single call? Unfortunately the following does not work:

textBlock.FontFamily = new FontFamily("ms-appdata:///Local/angsai.ttf,ms-appdata:///Local/angsa.ttf,ms-appdata:///Local/angsab.ttf#Angsana New");

Hello,

Welcome to Microsoft Q&A.

For system fonts which installed on the device (such as Segoe UI), a font family contains multiple fonts with different weights, which will be switched when calling TextBlock.FontWeight.

For custom fonts, the application will calculate based on the current font-weight instead of switching to another font.

This means that the text weights displayed by the following two TextBlocks may be different (even if the font files are in the same directory):

   <TextBlock FontFamily="ms-appdata:///Local/angsa.ttf#Angsana New" FontWeight="Bold" Text="Hello World"/>  
   <TextBlock FontFamily="ms-appdata:///Local/angsab.ttf#Angsana New" Text="Hello World"/>  

Therefore, for custom fonts, it is recommended to distinguish them by file, and different font-weight refer to different font files.

In addition, FontFamily.Source can be a path, but we cannot use , to separate multiple paths.

Thanks.
