FontTable

public class FontTable extends Object
FontTable or in MS terminology sttbfffn is a common data structure written in all Word files. The sttbfffn is an sttbf where each string is an FFN structure instead of pascal-style strings. An sttbf is a string Table stored in file. Thus sttbffn is like an Sttbf with an array of FFN structures that stores the font name strings
