On the Fonts tab in the dialog box of the ribbon command File | Options 
, you can specify which fonts are to be displayed in font lists (for example, the font list on the ribbon command Home | group Character).
The tab presents a list of all fonts installed on your system. To enable or disable a font in the list, click on the checkbox in front of its name. All fonts for which you have removed the check mark are no longer displayed in font lists.
Background information: The fonts installed on your system by default include several fonts that you will probably never need – for example, fonts that only contain scripts for foreign languages that you don't use. If you like, you can hide such fonts as described above.
Use font filtering of the operating system
Windows only: Windows users will also find the option Use font filtering of the operating system on this tab. If this option is enabled, Windows will automatically hide all fonts that only contain scripts for foreign languages in font lists.
