Greek Euro Support

System level support is provided for enabling the Euro within supported Greek locales.

In June 2000, Greece joined 11 other countries in adopting the Euro as their currency, with the complete transition effective as of January 1, 2002.

Summary of Change

Systems level support has been provided to allow for the input, storage, retrieval, display and printing of the Euro within the two supported Greek locales: el_GR.utf8 and el_GR.iso88597.

Greek Euro support has been provided in HP-UX 11i v1.6 via updates to locales, iconv converters, fonts, Xlib and CDE.

The level of Euro support provided for Greek is similar to that provided for Western European countries as of HP-UX 11.00 Extension Pack (May 1999) and HP-UX 11i v1.0:

Dual currency support using @euro modifier
Euro display and processing capabilities
Euro input capabilities in Greek locales
Printer support of Euro with other Greek characters

Details of Change

Euro-enabled Greek Locales:

The el_GR.utf8 and el_GR.iso88597 locales have been enhanced with the addition of 4 new characters, including the Euro:

Table 9-9 New Characters in Greek Locales

Character Name:	ISO-88597	Code Point Unicode	UTF-8
Euro	0xA4	0x20AC	0xE282AC
Drachma Sign	0xA5	0x20AF	0xE282AF
Greek Ypogegrammeni	0xAA	0x037A	0xCDBA
Greek Question Mark	0xAE	0x037E	0xCDBE

Also, the el_GR.utf8 locale binaries are now shipping as part of the release. Previously, only the el_GR.utf8 source file was provided for the user to build separately.

Locale-specific monetary processing and formatting:

When the LANG and/or LC_* environment variables are set to these Euro-enabled locales, the national monetary formatting rules are used to continue support for legacy (Drachma-based) applications. To access the monetary formatting rules for the Euro within the respective locale, the LC_MONETARY environment variable should be set to the desired locale name with the @euro modifier.

For example, to specify the Euro as the currency in the Greek UTF-8 locale, the following environment variables should be set to enable monetary formatting, such as used by strfmon(3C):

LANG=el_GR.utf8

LC_MONETARY=el_GR.utf8@euro

Data conversion (iconv) for Greek Euro:

Greek iconv converters have been updated to support the 4 new characters added to ISO-88597 (see table in Greek locales section) in conversions with UTF-8 and Unicode.

List of converter tables enhanced:

iso87 <-> ucs2

iso87 <-> utf8

Also, new iconv converters have been added to support data conversion between Greek EBCDIC (code page 875) and UTF-8/Unicode.

List of converter tables added:

greee <-> ucs2

greek <-> utf8

ISO-88597 and Greek EBCDIC converters have been enhanced to support Euro and have been aligned to match the expected mappings as defined by IBM for code page 875.

List of converter tables modified to align with expected mappings:

greee <-> iso87

The following table shows the modified code mapping changes made in converting from ISO-88597 to Greek EBCDIC / Code Page 875 (iso87=greee):

	NOTE: The following 3 characters currently have no Greek EBCDIC Code Page 875 code points defined. Consequently, in converting from either ISO-88597, Unicode or UTF-8, these characters is mapped to the Undefined Character for Greek EBCDIC (0xFF). These 3 characters are subject to data loss in round trip conversions between these codesets:

Table 9-12 Undefined Characters for Greek EBCDIC

ISO-88597	Greek Unicode	EBCDIC(CP 875)	Character
0xa5	0x20af	<undefined>	Drachma Sign
0xaa	0x037a	<undefined>	Greek Ypogrgrammeni
0xae	0x037e	<undefined>	Greek Question Mark

Displaying the Euro for Greek:

X11R6 Xlib has been enhanced to support the Euro when running in el_GR.iso88597 and el_GR.utf8 locales.

New font glyphs have been added to support the 4 new characters in ISO-88597. CDE is providing XlocaleDB for the el_GR.utf8 locale, and with this new XlocaleDB, el_GR.utf8 uses updated ISO-88597 fonts for displaying the euro.

Inputting the Euro for Greek:

Additional keymap support has been added to allow users of Greek-Latin keyboards to input the Euro symbol. The AltGr+5 sequence can be used with this new keymap (PS2_DIN_Greek_Euro) to input the Euro character.

Alternatively, users with US English keyboards can use the PS2_DIN_US_English_Euro keymap where the Euro symbol is mapped to AltGr+4.

CDE provides support to input and display the euro in the iso8859-7 locale.

The additional 3 characters do not have keybindings in any Xserver keymaps. The reason for this is that there is no standard definition among the X Window vendors on which key sequences should activate those other symbols. As a result, they are assigned key bindings whenever the mappings are clarified by the industry.

Printing Euro with Greek characters:

The standard lp command is used to print Euro and Greek characters on LaserJet printers. The LaserJet printers should have the resident Greek character/font set with the Euro symbol included. Current LaserJet printer models with this support include the LaserJet 1220 and the LaserJet 2200.

Use the lp command with the -ocs12N option to select the Greek character/font set. For example:

lp -d [printer_name] -ocs12N -o [other_options] [print_filename]

Impact

Base Greek Euro offering (installed on all systems): Approximately 14.2MB additional disk space is required.

No additional memory requirements are needed for running in either the el_Gr.iso88597 or el_GR.utf8 locales.

Compatibility

Iconv conversion between ISO-88597 and Greek EBCDIC (CP 875) yields different results than in previous releases. In HP-UX 11i v1.6 , these tables have been corrected to provide the correct conversion mappings.

It is recommended that all Greek-encoded legacy persistent data stored on previous versions of HP-UX be converted to ISO-88597 from Greek EBCDIC prior to being moved to an HP-UX 11i v1.6 system.
