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.
|
|
