Abstract
A method for examining font files for corruption involves an font manager communicating with a remote font server which stores uncorrupted font files. A portion of the font file to be checked for corruption may be compared with the uncorrupted font file to determine whether the file is corrupted. If the file is corrupted, an uncorrupted font file may be downloaded to the font manager to replace a portion of the corrupted font file containing the actual font file as opposed to a portion of the font file which may include other information such as kerning information.
