iOS 13 Font bugs

[ichan-mb]

Describe the bug
Default fonts (using system font) on iOS 13 look terrible, it's bigger and spacing between character is so wide and space character is also wide. I assume Fuse doesn't pick up default system font family or default system font path

To Reproduce
Compile this code on Xcode 11 and targeting iOS 13

<App>
	<ClientPanel>
		<StackPanel Alignment="CenterLeft" ItemSpacing="5">
			<Text Value="This is sample text" Font="Thin"/>
			<Text Value="This is sample text" Font="Light"/>
			<Text Value="This is sample text" Font="Regular"/>
			<Text Value="This is sample text" Font="Medium"/>
			<Text Value="This is sample text" Font="Bold"/>
			<Text Value="This is sample text" Font="ThinItalic"/>
			<Text Value="This is sample text" Font="LightItalic"/>
			<Text Value="This is sample text" Font="Italic"/>
			<Text Value="This is sample text" Font="MediumItalic"/>
			<Text Value="This is sample text" Font="BoldItalic"/>
		</StackPanel>
	</ClientPanel>
</App>

Expected behavior
Displaying default system font (San Fransisco Font) with correct weight and styles

Yeah, looks like somehow a monospace font gets picked up instead. That's odd, and will require some debugging on an iOS device. Sadly, I don't have access to a mac or iOS device any longer...

Hey guys,

I noticed this when I switched between fuselibs and used uno doctor:

Had a look for Uno.Content.Fonts.CharacterSets and found this: https://github.com/fuse-open/uno/blob/8582e76cd9de40a8568ca757837cdc64211c9403/lib/UnoCore/Source/Uno/Content/Fonts/FontFaceHelpers.uno

Could this be the cause @mortend? 😄

...or not, I'm looking into another hunch... 😸
