+
+CMap (Character Map) resources are used to unidirectionally map character codes,
+such as Unicode encoding form, to CIDs (Character IDs -- meaning glyphs) of a
+CIDFont resource.
+
+These CMap resources are useful for some applications (e.g. Ghostscript) to
+correctly display text containing Japanese, (Traditional) Chinese, or Korean
+characters.
