Foreword	Réamhrá
This Irish Standard has been prepared by NSAI/AGITS/WG6. It is based on and, by exercising the options permitted, is fully in conformity with ISO/IEC 8859:1991 Information technology - ISO 8-bit coded character set for information interchange.	Caighdeán Éireannach é seo a cruthaíodh ag NSAI/AGITS/WG6. Baineadh leas as roghanna ceadaithe ISO/IEC 8859:1991 Information technology - ISO 8-bit coded character set for information interchange, agus tá sé ag teacht go huile is go hiomlán leis an gcaighdeán sin.
Compliance with an Irish Standard does not of itself confer immunity from legal obligations.	Ní leor ann féin, mar imdhíonadh ar oibleagáidí dlí, a bheith ag teacht le Caighdeán Éireannach.

Specification	Sonraíocht
1 Scope	1 Scóip
This Irish Standard specifies an 8-bit Ogham coded character set which is derived from the ISO 8-bit coded character set as described in ISO/IEC 8859-1:1991.	Sonraítear sa Chaighdeán Éireanneach seo tacar carachtar Oghaim, códaithe le 8 ngiotán, bunaithe ar an tacar códála carachtar códaithe le 8 ngiotán a leagtar síos faoi ISO/IEC 8859-1:1991.
This standard specifies a character set for the Ogham script, which will satisfy the needs of professionals and amateurs interested in Ogham by providing a standard encoding for Ogham texts. The left-hand part of this character set is identical to that of ISO/IEC 8859-1. The right-hand part of this character set conforms to that of the repertoire accepted for inclusion in ISO/IEC 10646. In any 8-bit implementation of the Ogham script, the code table specified here should be used, whether the implementation environment be Macintosh, DOS, Windows, UNIX, or any other platform. When transferring text from platform to platform, no character transformation should be performed.	Sonraítear sa chaighdeán seo tacar carachtar do script Oghaim, a shásóidh riachtanais daoine gairmiúla agus daoine amaitéaracha a bhfuil spéis acu san Ogham, agus chun códú caighdeánach do théacsanna Oghaim a chur ar fáil. Is ionann an taobh chlé den tacar carachtar seo agus an taobh chlé de ISO/IEC 8859-1. Is ionann stór an tacar 8 ngiotán carachtar seo agus an stór a glacadh isteach in ISO/IEC 10646. I ngach comhlíonadh 8 ngiotán an Oghaim, úsáidtear an tábla códála atá sonraithe anseo, cé acu atá an suíomh comhlíonaithe, .i. Macintosh, DOS, Windows, UNIX, nó suíomh ar bith eile atá i gceist. Ba cheart gach carachtar a thabhairt slán gan aon athrú le linn téacs a aistriú ó thimpeallacht ríomhaireachta amháin go timpealleacht eile.
This set of coded graphic characters is intended for use, both nationally and internationally, in data and text processing applications and may also be used for information interchange.	Lena úsáid i bhfeidhmchláir próiseála téacs agus sonraí a chuirtear an tacar códaithe carachtar grafach seo ar fáil. Is féidir é a úsáid i malartú eolais chomh maith, i gcomhthéacs naisiúnta agus idirnáisiúnta.
This set of coded graphic characters may be regarded as a version of an 8-bit code according to ISO/IEC 2022 or ISO/IEC 4873 at level 1.	Is féidir caitheamh leis an tacar códaithe carachtar grafach seo mar leagan de chódú 8 ngiotán faoi réir ag ISO/IEC 2022 nó ISO/IEC 4873 ag leibhéal 1.
The font design of characters is not specified in this standard. A guide to implementors of Ogham fonts, is, however, provided in the informative Annex.	Ní shonraítear sa chaighdeán seo dearadh chruth na gcarachtar i gclófhoirne, ach tá treoir do lucht déanta clófhoirne, ar fáil mar eolas san Aguisín.

A guide to Ogham font implementors

Aguisín (Mar eolas)
Treoir do lucht déanta clófhoirne Oghaim

Monumental Ogham was incised on stone chiefly in a bottom-to-top direction, though there are examples of left-to-right bilingual inscriptions in Irish and Latin. Manuscript Ogham accommodated the horizontal left-to-right direction of the Latin script and the vowels were written as vertical strokes as opposed to the incised notches of the inscriptions. Ogham should therefore be rendered on computers from left-to-right, or from bottom-to-top (never starting from top-to-bottom). Gearraítí Ogham na Liag aníos ó bhun go barr cloiche, ach tá inscríbhinní dátheangacha Gaeilge agus Laidine ann a théann ó chlé go deas. Leanann Ogham na Lámhscríbhinní gnath-threo na Laidine (cothrománach agus ó chlé go deas), le stríocanna ingearacha in áit eangaí greanta na n-inscríbhinní le haghaidh na ngutaí. Ar an ábhar sin ba cheart Ogham a léiriú ar ríomhairí ó chlé go deas ó thús, nó ó bhun go barr (seachas ó bharr go bun).

1. The centre line is optional. In printing and in manuscript Ogham it is conventional to design with a centre line, but this is not necessary. In implementations without the centre line, the character OGHAM SPACE MARK should be given its conventional width, and simply left blank like SPACE. 1. Cuid roghnach den chló is ea an líne láir. Is gnách líne láir a úsáid in Ogham na lámhscríbhinní agus sa chlódóireacht, ach ní gá sin. Nuair nach bhfuil líne láir in úsáid, ba cheart charachtar COMHARTHA OGHAIM SPÁS a dhearadh ar an ngnáthleithead, ach é a fhágaint bán ar aon dul le SPÁS.

2. Left-to-right orientation is recommended. Early Ogham font implementations often provided two different Ogham character encodings within a font, one with horizontal orientation and one with vertical. It is recommended to implement horizontal orientation for both Latin and Ogham characters in Ogham fonts, and to rotate the text in its entirety when bottom-to-top display is required. 2. Dearadh ó chlé go deas molta. Sna clófhoirne Oghaim is luaithe is minic a cuireadh códú dúbailte ar fáil in aon chlófhoireann amháin, ceann cothrománach agus ceann ingearach. Moltar treoshuíomh cothrománach a chur i bhfeidhm ar na carachtair uile idir Laidin agus Ogham i gclófhoirne Oghaim, agus an téacs féin a rothlú lena léiriú ó bhonn aníos.

3. Balance Ogham with the Latin characters. Ogham "x-height" doesn't really exist, but centring the characters between the ascender of "d" and the descender of "p", with the centre line at or slightly above the cross of "x" usually yields a a balanced result. Sometimes OGHAM LETTER EAMHANCHOLL is made to ascend a bit higher than the top of the em-square but this is acceptable. 3. Cruthaigh cóimheá idir carachtair Oghaim agus cuid na Laidine. Níl a leithéid de rud agus "airde x" san Ogham, ach moltar na carachtair a lárlonnú idir líne aníos an "d" agus líne anuas an "p", leis an líne láir ar aon airde le trasnán an "x", nó beagáinín os a chionn. Is féidir leat ligint do LITIR OGHAIM EAMHANCHOLL éirí níos airde ná barr na cearnóige eim, más maith leat.

5. Ogham keyboards. Ogham keyboard drivers should access the Ogham characters when Shift-Lock is engaged, according to the arrangement below.

5. Luibheanchláir Oghaim. Ba cheart go ndéanfadh tiománaithe luibheanchlár Oghaim carachtair Oghaim a rochtain agus Malairt Glasta ar siúl, de réir an leagan amach thíos.

6. Non-Ogham characters. Font implementors may wish to include several non-Ogham characters for the convenience of users, as some applications may use them for display of invisible characters or other purposes. While the encoding of these characters is outside the scope of this platform-independent standard, the following positions are recommended as being suitable.

6. Carachtair nach mbaineann leis an Ogham. Font implementors may wish to include several non-Ogham characters for the convenience of users, as some applications may use them for display of invisible characters or other purposes.
