coding of this file was nonstandard. The following is a translation I used to extract the table of contents:
ABCDEFGHIJKLMNOPQRSTUVWXYZ [first character is a space]
I am working to identify this coding or font, because copy and paste from these documents generates what looks like garbage, but which is merely character-translated, apparently. If I can identify it I may be able to find or create a translator and make it possible to copy material for study into ordinary documents.
