Make a script export a report of fonts included in a mxd. Useful not to forget which font to include when changing computer. Be able to parse a folder for mxd and make a report of fonts use by mxd and a summary of fonts use in that directory.
The same with Pro Aprx project.
This has been marked by Kory Kramer as a duplicate of Have ArcMap be able to list all the fonts used for character marker symbols, etc. (aka font metadata)
