Normally, the key is converted to lowercase before being stored in
the database makemap. When the key entries are
case-sensitive, the -f switch is used by
makemap to prevent conversion to lowercase. This
-f command-line switch causes
editmap to match that behavior when looking up a
key. When the -f is absent, the key specified in
the command line is converted to lowercase before it is looked up. If
the -f is present, the key is looked up as is.
In general, if the configuration file's
corresponding K command for a database uses the
-f, you should also use -f when
running editmap on that database file.
