Summary: Contains basic information about a physical font.

!!!!C# Definition:

/*
	Since a type 'char' is stored in .NET within 2 bytes, but the Win32 API assumes
	that the type 'char' is stored within 1 bytes, it will cause compatibility problems
	to use the 'char' keyword by the definition of this structure. 
	Important: If you keep the 'char' keyword, then the whole data after tmFirstChar
	will be offsetted by 4 bytes!
	Hint: use byte keyword and convert the characters programmically later on to use it.
