+Subject: [PATCH] Deal with different VM modes during CIDFont loading
+
+To help differentiate between a substituted CIDFont and an embedded one, a
+change was made to store the file path in the CIDFont dictionary. That change
+failed to account for the possibility that the file object and the CIDFont
+dictionary may not be in compatible VM modes.
+
+This adds code to ensure that the string holding the path is in a suitable VM
+mode to be stored into the dictionary.
+
+Reported by Richard Lescak <rlescak@redhat.com>
