euro, Euro, EUR - Euro currency sign
The Euro currency is the new currency for European countries
belonging to the Economic and Monetary Union (EMU).
Euro currency was introduced in 1999. By January 2002, the
new currency is scheduled to replace local currencies for
most EMU member countries.
The Euro currency has its own euro currency sign, which
looks like an equal sign (=) superimposed on the capital
letter C. Several character sets have been updated or
invented to include the euro character. Among these are:
Unicode Version 2.1 or later. The euro currency sign was
not defined in Unicode codesets prior to the Version 2.1
Unicode standard. Implementations of Unicode encoding formats
based on pre-2.1 versions do not include the euro
character. ISO/IEC 8859-15 (Latin-9) Certain DOS and
Microsoft code pages
If your character set does not support the euro character,
you can prepend the string EUR before monetary amounts in
Euro currency in the same way USD is sometimes used to
specify U. S. dollars in certain kinds of financial
reports.
The following table specifies the encoding position of the
euro character in each of these character sets:

Locales That Support the Euro Character [Toc] [Back]
Tru64 UNIX locales that support the euro character use
either the UTF-8 or ISO 8859-15 codeset. The following
table lists these locales by language and country:
ca_ES.UTF-8, ca_ES.ISO8859-15 zh_CN.UTF-8 zh_HK.UTF-8

locale that is explained following the list.)

sv_SE.UTF-8, sv_SE.ISO8859-15 tr_TR.UTF-8
From the Options menu of the Login window, CDE users can
choose locales by using the Language menu and choosing
languages whose names are followed by "(Unicode)." Alternatively,
users can set the LANG environment variable to
one of the locales in a terminal emulation window. The
Latin-9 locales can be set in a terminal emulation window.
When set in a terminal emulation window, the locale setting
applies to child applications subsequently invoked
from that window.
The @euro locale variants provide LC_MONETARY definitions
for the euro character and are intended for assignment
specifically to the LC_MONETARY locale variable. In these
locales, the local currency sign is defined to be the euro
character and the international currency sign is defined
to be EUR. In addition, the LC_MONETARY definition is set
to the euro character for the and locales of the languages
that have fully adopted the euro; see l10n_intro(5).
Because the euro character is not in the Latin-1 character
repertoire, the (Latin-1) locales for these languages continue
to use the pre-euro local currency; lira in Italian,
for example.
The en_US.UTF-8@euro locale defines the radix point to be
the period (.) and the thousands separator to be the comma
(,). The en_EU.UTF-8@euro locale reverses these character
assignments; the radix point is a comma (,) and the thousands
separator is a period (.). Because en_EU.UTF-8@euro
is intended for assignment only to LC_MONETARY, the locale
is useful for languages other than English. For example,
support for the euro character in Poland can be obtained
by setting LANG to pl_PL.UTF-8 and LC_MONETARY to
en_EU.UTF-8@euro.
Note
The LC_ALL environment variable overrides settings of all
locale category variables, such as LC_MONETARY. When setting
LC_MONETARY to be different from settings for the
remainder of locale categories, be sure to use the LANG,
not the LC_ALL, environment variable.
Applications that currently assume that 1 character of
data is represented by 1 byte of data in file code can
more easily support the euro character by running in a
locale rather than a locale. Because UTF-8 is basically a
multibyte character encoding format, programmers cannot
assume that 1 character is equal to 1 byte of input data.
To run in a locale, applications should use functions that
handle multibyte and wide-character data rather than older
functions that operate only on single-byte characters. See
Writing Software for the International Market for more
information on this topic. See Unicode(5)for more information
about UTF-8 encoding formats.
Codeset Converters That Support the Euro Character [Toc] [Back]
Codeset converters are available to convert data between
encoding formats that support the euro character. Codeset
converters can convert file data between the following
formats: Unicode encoding formats and the 874 and 125*
code pages Unicode encoding formats and ISO 8859-15
(Latin-9)
For more information about these codeset converters, see
iconv_intro(5), Unicode(5), code_page(5), and
iso8859-15(5).
Keyboard Entry of the Euro Character [Toc] [Back]
Depending on locale setting and keyboard style, you can
use particular key sequences to enter the euro character.
When using a or locale and a keyboard that supports the
Compose-character entry method, you can use the Compose
key input method to enter the euro character. For Composekey
input, you press and release certain keys in sequence,
starting with the key defined as the Compose key. For the
euro character, use one of the following two sequences:
Compose C = Compose = C
Left Compose+E is the most efficient key sequence for
entering the euro character on VT-style keyboards in all
languages that support the euro (except for the United
Kingdom). In the United Kingdom, the VT-style keyboard
sequence is Left Compose+4.
Right Alt+E is the most efficient key sequence for entering
the euro character on PC-style keyboards in all languages
that support the euro (except for the United Kingdom).
In the United Kingdom, the PC-style keyboard
sequence is Right Alt+4.
The key sequences are supported only by xkb format keymaps
(which are the default for CDE users). When using these
key sequences, you hold down the first key while pressing
the other.
See keyboard(5) for more information about keyboards,
keymaps, and character entry modes.
Font Support for the Euro Character [Toc] [Back]
The operating system does not provide native Unicode fonts
that include glyphs for the euro character. However, the
character is supported by a set of Latin-9 fonts. The X
font library has been extended to combine a number of
fonts together to provide logical Unicode fonts for applications
to use. The names of these logical fonts end with
ISO10646-1. You can use the xlsfonts utility to find out
if these fonts are installed on your system.
Printer Support for the Euro Character [Toc] [Back]
Printing of file data in UTF-8 or Latin-9 format is supported
by a generic PostScript print filter. See wwpsof(8)
for information on how to configure this print filter.
Commands: xlsfonts(1X), wwpsof(8)
