Epson Printer Interface Cartridge for the Apple IIc Operation Manual page 36

Once you have selected an international character set with the DIP
switches or the ESCape "R" code, you can use the tables to see which
keys on your standard keyboard can produce the international char-
acters you want. Simply type the character from the top row of one of
the figures in order to print the corresponding character in the row of
the set you have chosen.
For example, if you have reset the DIP switches for the UK charac-
ter set and you press the # key, the £ symbol will be generated. Even
though you will see the # symbol on the screen, the £ symbol will be
printed on the paper. For another example, if you have selected the
Swedish character set and you press the @ key, the É symbol will be
generated.
