• the controller being further configured to:
• cause the display unit to display, when the first document data is received through the data input unit, and the character strings expressed by the first document data include the first character string containing the misspelling, a second character string that may possibly be substituted for the first character string;
• and
• generate, upon receipt of an instruction to select the second character string through the instruction input unit, second document data on a basis of the first document data, by substituting the first character string in the character strings expressed by the first document data, with the second character string selected.
