Appendix B: Encoding Names
Supported encoding names
The following list of names is a basic set of encoding names supported by the FileSystem object. Some of the
character encoders are built in, while the operating system is queried for most of the other encoders.
Depending on the language packs installed, some of the encodings may not be available. Names that refer to
the same encoding are listed in one line. Underlines are replaced with dashes before matching an encoding
name.
Note, however, that the FileSystem object cannot process extended Unicode character with values greater than
65535. These characters are left encoded as specified in the UTF-16 standard in as two characters in the range
from 0xD700-0xDFFF.
Built-in encodings are:
U S - A S C I I, A S CI I , ISO646- US, I SO-646. I RV: 1991, ISO- IR- 6 , AN S I -X 3 . 4 -
1 9 68 ,C P367, IB M367, U S, ISO646. 1991- I RV
U C S - 2, UC S 2, I SO-10646-U CS- 2

U C S - 4, UC S 4, I SO-10646-U CS- 4

The ASCII encoder raises errors for characters greater than 127, and the BINARY encoder simply converts
between bytes and Unicode characters by using the lower 8 bits. This encoder is convenient for reading and
writing binary data.
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, for example, 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 Mac OS, encoders may be selected by name rather than by code page number. The File object queries Mac
OS directly for an encoder. As far as Mac OS character sets are identical with Windows code pages, Mac OS
also knows the Windows code page numbers.
