How to use customized code page in AFP font

The customer asked their client to provide the fonts from the IBM system but they claim it is in a format which they cannot use. They want to reference these fonts in the AFP which they do not have locally on their system (Doc1 Designer).
The customer is going to extract the code page via Doc1rpu, change the name of the code page to match their customer's (using 3rd-party software such as Font Lab), and then map to that code page using the User Defined Resource Map.
