1. A character combining method for combining a character pattern of a first typeface with a character pattern of a second typeface to generate a character pattern of a third typeface, the method comprising steps of: providing a first plurality of part patterns for each character pattern of the first typeface; providing a second plurality of part patterns for each character pattern of the second typeface; providing a plurality of common typeface structure codes corresponding to respective part patterns of said first and second plurality and affixing a common typeface structure code to each part pattern of said first and second plurality wherein a respective common typeface structure code affixed to a corresponding part pattern is identical for the first and the second typeface; searching, from said first and second plurality of part patterns, for corresponding part patterns for the character pattern of said first typeface and the character pattern of said second typeface, based on identical common typeface structure codes affixed to said corresponding part patterns; and combining said corresponding part patterns to prepare part patterns of a character pattern of said third typeface.
