New description:

 The automatically generated `WCsubst.c` was last generated in 2011. The
 Unicode standard has been updated several times since then. I would like
 to try to replace that whole mechanism with something a little more cache-
 friendly, but at the very least the tables need to be right.
 Unfortunately, the script that generates this file gives no information
 about its input format, or just where a file with the right format is
 supposed to come from.
