A font face reference consists of a font file, font face index, and font face simulation. The file data may or may not be physically present on the local machine yet.

IDWriteFontFamily1	Represents a family of related fonts.
IDWriteFontFamily2	Represents a family of related fonts. IDWriteFontFamily2 adds new facilities, including retrieving fonts by font axis values.
IDWriteFontFile	Represents a font file. Applications such as font managers or font viewers can call IDWriteFontFile::Analyze to find out if a particular file is a font file, and whether it is a font type that is supported by the font system.
IDWriteFontFileEnumerator	Encapsulates a collection of font files. The font system uses this interface to enumerate font files when building a font collection.
IDWriteFontFileLoader	Handles loading font file resources of a particular type from a font file reference key into a font file stream object.
IDWriteFontFileStream	Loads font file data from a custom font file loader.

It allows the separation between the logical view of text as a continuous stream of characters identifiable by unique text positions, and the actual memory layout of potentially discrete blocks of text in the client's backing store.
IDWriteTextAnalysisSource1	The interface you implement to provide needed information to the text analyzer, like the text and associated text properties.
IDWriteTextAnalyzer	Analyzes various text properties for complex script processing such as bidirectional (bidi) support for languages like Arabic, determination of line break opportunities, glyph placement, and number substitution.
