Font Repository
Overview
A text font defines how texts are graphically displayed.Every text font in a project is stored only once; also if you use the font in multiple objects. Text fonts are stored in a database called the Font Repository.
Details
If you add text fonts to a project, you may give the font a free name. It is recommended to give a name that describes the purpose of the font, and not a name that describes the font. The reason for that is that you may want to change the font later (because another font looks better). If you would have described the font in its name, then the name would not fit anymore.So, examples of good naming would be: Page Title Font, or Viewer Header Font.
The font references can be edited in a special dialog: link.
