Insert the Office app creation file (e.g. PowerPoint) into Confluecne or JIRA "Add a picture, movie, or file" and save it. When the file is previewed (not downloaded) in the display mode, the contents of the file can be browsed, but the display character font at that time becomes a special style (More of a Chinese-style display that you don't often see in Japan) which is not familiar. The downloaded file displays the correct (intended) fonts. Is there a way to display the correct font as intended in the preview?
