and NT systems
DESCRIPTION
Code pages are coded character sets that are used on Microsoft Windows,
Windows 95, and NT systems. Just as there are different UNIX codesets,
there are different PC code pages, each supporting a particular set of
character encodings.
A DIGITAL UNIX system supplies one locale, en_US.cp850, that directly
supports a PC code-page format (MS-DOS Latin 1). For all other locales,
data in code-page format is supported only through codeset converters.
These converters can be run directly by users or by software or
applications that exchange data between PC and DIGITAL UNIX systems. Fonts
and other kinds of character support are available only for the native UNIX
codeset to which a code page can be converted. See the i18n_intro(5)
reference page for introductory information on locales and codesets. See
the iconv_intro(5) reference page for an introduction to codeset conversion
and the name format and location of codeset converters.
The following table lists and describes the code pages that have conversion
support on a DIGITAL UNIX system. An asterisk (*) follows the names of code
pages that include support for the Euro currency sign (C=).

(1) Baltic languages include Estonian, Latvian, and Lithuanian.
(2) Latin-2 languages include Albanian, Croatian, Czech, Faeroese,
Hungarian, Polish, Romanian, Latin Serbian, Slovak, and Slovenian.
(3) Cyrillic languages include Byelorussian, Bulgarian, and Russian.
In all cases, a code page can be converted to and from the UCS-2, UCS-4,
and UTF-8 codesets. In addition, some code pages can be converted directly
to ISO codesets as shown in the following table, although some data loss
may occur.

_________________________________________
See Unicode(5) for information about UCS-2, UCS-4, and UTF-8. Reference
pages for UNIX implementations of the ISO codesets have the name format
iso8859-number(5).
For Traditional Chinese and Japanese, there are no codeset converters whose
names include the name of a code page because identical character encoding
is provided in existing UNIX codesets. For Traditional Chinese, character
encoding in PC code-page format (cp950) is identical to that in the Big-5
(big5) codeset. For Japanese, character encoding in PC code-page format
(cp932) is identical to that in the Shift JIS (SJIS) codeset. Therefore,
the codeset converters whose names include big5 and SJIS can be used to
convert data in and out of PC code-page format for the supported languages.
Caution for Conversion of Korean and Simplified Chinese
Conversion of text that starts out in code-page format (cp949) to the
DEC Korean (deckorean) codeset may result in loss of data. All of the
DIGITAL UNIX codeset equivalents for cp949 support all the Hanja and
miscellaneous characters also supported by the code page. However,
only the UCS-2, UCS-4, and UTF-8 codesets support the complete set of
Hangul characters supported by the cp949 code page. The deckorean
codeset supports only a subset of these Hangul characters. Therefore,
if data is converted from cp949 format to UCS-2, UCS-4, or UTF-8, no
data is lost. However, if the data is then converted from UCS-2, UCS-
4, or UTF-8 to deckorean, the unsupported Hangul characters will be
lost.
The DEC Hanzi (dechanzi) codeset uses the same encoding format as the
PC code page used for Simplified Chinese (cp936) but does not support
all the characters supported by the code page. Therefore, you can use
converters with dechanzi in the converter name to convert text to and
from cp936 format, but the operation may result in some loss of data.
