FontExpert ignores corrupted fonts and does not add them to library.
It does not provide a list of corrupted fonts during "Add to Library" procedure, but it writes all paths to all corrupted fonts in the log files:
C:\Users\<USER NAME>\AppData\Roaming\Proxima Software\FontExpert\14.0\LIB\AddFontsToLibrary-Report.txt
C:\Users\<USER NAME>\AppData\Roaming\Proxima Software\FontExpert\14.0\LIB\AddFontsToLibrary-Report 2.txt
C:\Users\<USER NAME>\AppData\Roaming\Proxima Software\FontExpert\14.0\LIB\AddFontsToLibrary-Report 3.txt
etc.
It creates log after each Add to Library operation.
Anther way to find corrupted fonts is easier.
Use
Find Fonts window to detect corrupted fonts.
