UNABLE_TO_MASK_PATH exception thrown when constructing CanvasFontSet

[SuGar0218]

When the path to the font file is too long, a COMException with message "UNABLE_TO_MASK_PATH" will be thrown. I have enabled "LongPathsEnabled" in regedit and declared "longPathAware" in app.manifest.

<application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
        <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>
        <longPathAware xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">true</longPathAware>
    </windowsSettings>
</application>
