[comp.std.internat] what's the standard Turkish character set?

jack@cs.glasgow.ac.uk (Jack Campin) (01/15/91)

Could somebody tell me what the ISO standard Turkish alphabet is?

Or, at least, the codes for the non-ASCII characters.

Someone had posted someting along these lines to TEL once. I 
looked around my files but I couldn't find it. Is there anyone
who has any ideas about this.

What I remember was that there was a proposal for one of the ISO
alphabets to have some Turkish characters in lieu of some characters
from the Scandinavian-Danish character set.

Does anyone have any ideas on this ??

There isn't an "ISO standard Turkish alphabet".  However, ISO 8859-9
(Information processing -- 8-bit single-byte coded graphic character sets -- 
Part 9: Latin Alphabet No. 5; note the difference in numbers) is the member of
the ISO 8859 family of eight-bit codes designed to represent Turkish text.

ISO 8859-9 was based on ECMA standard ECMA-128 which was based on a Turkish
industrial standard whose number I no longer have in my notes.  As another
poster suggested, it is very similar to ISO 8859-1 (ISO Latin Alphabet No 1). 

Differences from ISO 8859-1 are as follows:

13/00  CAPITAL LATIN LETTER G WITH BREVE
13/13  CAPITAL LATIN LETTER I WITH DOT ABOVE
13/14  CAPITAL LATIN LETTER S WITH CEDILLA
15/00  SMALL LATIN LETTER g WITH BREVE
15/13  SMALL LATIN LETTER i WITHOUT DOT
15/14  SMALL LATIN LETTER s WITH CEDILLA

The capital and small ICELANDIC LETTER ETH, ICELANDIC LETTER THORN, and LATIN
LETTER Y WITH ACUTE ACCENT are removed. 

[ISO 8859-3 also was designed for this purpose but no one likes it very much. 
This code was originally developed in Turkey to be as similar as possible to
ISO 8859-1 to leverage off of the wide support for ISO Latin-1.   There are
occasional attempts to get this code to be the "favored" (in lieu of ISO
8859-1) eight-bit code in various standards forums, none successful to date, to
my knowledge.]
