how after effcts check the missing fonts?

i want to check the missing fonts when i launch the project, just like the after effects.

how after effects do this?

i collect the system fonts, but i find it doesn`t collect all the fonts. some of them are not collected.

let content = `
                [System.Reflection.Assembly]::LoadWithPartialName('System.Drawing');
                $fonts = New-Object System.Drawing.Text.InstalledFontCollection;
                $list = [System.Collections.ArrayList]@();
                foreach ($font in $fonts.Families){ $idx = $list.Add($font.Name); } 
                ConvertTo-Json($list)>$env:temp/fontlist.json;`;
child_process.spawn('powershell.exe', ['-c', `${content}`]);

is there a extendscript api can check the missing fonts or any other way to do this?

thanks for any help.
