— Function: font-specifier-p object

This predicate returns t if object is a font specifier, and nil otherwise.

— Function: make-font-specifier spec-list

Return a new font specifier object with the given specification list. spec-list can be a list of specifications (each of which is a cons of a locale and a list of instantiators), a single instantiator, or a list of instantiators. See Specifiers, for more information about specifiers.

Valid instantiators for font specifiers are:

• A string naming a font (e.g. under X this might be "-*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*" for a 14-point upright medium-weight Courier font).
• A font instance (use that instance directly if the device matches, or use the string that generated it).
• A vector of no elements (only on TTY's; this means to set no font at all, thus using the "natural" font of the terminal's text).
• A vector of one element (a face to inherit from).
