CONTENT CREATION DEVICE, CONTENT DISPLAY UNIT, AND DATA PROCESSOR

PROBLEM TO BE SOLVED: To create content using a character set desired by a creator. SOLUTION: When content data is created, a conversion part 411 analyzes/inspects that a character included in descriptive content data in a descriptive content data memory 408 is included in a character set being a subset of a universal set of character codes indicated by a character set content information memory 409 and a character set information memory 410, thereby preventing inclusion of a character unintended by the content creator in the content. In addition, a content display unit inspects whether identification information on the character set included in the descriptive content data matches identification information on a character set of installed external fonts to decide whether the character set can be displayed, thereby preventing transformed characters or the like during display.
