Abstract: This invention can provide an information processing apparatus and control method thereof, and a program, which can efficiently execute processing associated with font settings. To accomplish this, font information of a first character and font information of a second character, which are located before and after the position of an input character are acquired. When the acquired font information of the first character and the acquired font information of the second character include the same font type, the font type is set as font type information used for the input character. When the acquired font information of the first character and the acquired font information of the second character include different font types, parsing is executed for the character string including the input character, and font type information used for the input character is set based on the parsing result.
