Additional encodings

In Windows, all encodings use so-called code pages. These code pages are assigned numeric values. The usual Western character set that Windows uses is e.g. the code page 1252. Windows code pages may be selected by prepending the number of the code page with "CP" or "WINDOWS- like "CP1252" for the code page 1252. The File object has a lot of other encoding names built-in that match predefined code page numbers. If a code page is not present, the encoding cannot be selected.

On the Macintosh, encoders may be selected by name rather than by code page number. The File object queries the Macintosh OS directly for an encoder. As far as Macintosh character sets are identical with Windows code pages, the Macintosh also knows the Windows code page numbers.
