Comment 22 for bug 324256

The problem is caused by the em dash appearing in rcm.c as a unicode character while the program uses one-byte encoding in its internals and converts it to unicode while producing the output. The included patch solves the issue.
Other suspicious places in the source that may cause issues similar to this are line 550 of Kern/rstr/src/rcm.c and line 98 of Kern/rling/sources/c/speldict.c.
