Getting Started with Custom Fonts
Custom fonts allow users to extend the list of fonts available in the Format dialog by registering new font names. The font names are stored in the Form/View definition when implemented, making it unnecessary to register the custom font names in other environments when the Forms/Views are deployed.
Registering a custom font will NOT install that font on the operating system (for example adding the font to the windows fonts), as the custom font function only adds the font name to the list of fonts to select from. If you wish to make use of custom fonts, you need to ensure that the font is distributed and installed in all K2 servers, client machines and any other machine used to access the runtime site.
The documented procedure does not register the Font on users' computers: it only makes the font available in the Format dialog. It is up to your organization to ensure that the Font is distributed to user machines and servers appropriately.
