+
+ This function is called in these two cases:
+
+ (1) A charset has a mapping file name in :map property.
+
+ (2) A charset has an upper code space in :offset property and a
+ mapping file name in :unify-map property. In this case, this
+ function is called only for characters in the Unicode code space.
+ Characters in upper code space are handled directly in
+ map_charset_chars. */
