-Sometimes CMaps define mappings which are not covered by the codespace ranges. This can be seen very often in the wild. These illegal mappings are collected into the ''#unmapped'' variable of a Mappings object.
+Here are single byte mappings in a double byte codespace which is not correct according to the documentation.
-==== Wrong PostScript ====
+This can be seen often. These illegal mappings are collected into the ''#unmapped'' variable of a Mappings object.
-using /find instead of /findresource
+==== Wrong PostScript ====
-See [[postscript#exception_handling_example]]
+On one occasion, I saw a CMap where the PostScript used a non-existing operator (''/find'' instead of ''/findresource''). See the [[postscript#exception_handling_example]] on the PostScript page.
