Assigning the Codepage
In the Codepage submenu you can see three common commands and a
list of Macintosh codepage names:
Use Default
Use the destination codepage selected as the default in the Preferences
dialog.
Unicode
Is not usable in the case described here.
Leave as is
Do not reencode the source font – any selection in the Source list pop-up
menu is ignored.
A list of potential codepages to which the font can be reencoded follows
these three commands. The number of available codepages depends on the
number of characters in the font.
When TransType finally gets the information about the Unicode indexes to
which the font characters are mapped (from the font or after you have
assigned a codepage to the source font), it knows which destination
codepages this font can support and shows only these codepages in the
destination encodings menu.

Tip: To force TransType to include all the possible codepages, press and
hold down the Ctrl key.

Tip: It is possible to change the destination codepage for multiple selected
items in the Destination list at once. But you must right-click on the
selection instead of using the pop-up menu button at the right of the font
name.
