US Patent 7937658 Methods and apparatus for retrieving font data

A message processor receives message data from a remote source for rendition to a user of a computerized device. The message processor renders the message data to the user and, during rendering of the message data, identifies that a font in which the message data is to be rendered is missing font portions required to fully render the message data in that font. In response, the message processor dynamically obtains the missing font portions for that font to allow the computerized device to fully render the message data in that font.
