Talk:ISO/IEC 646

ISO 646
ISO 646 should be ISO/IEC 646; similarly for 8859 and 10646. Presumably page names can't include a slash; is there some convention for representing this? In any case, since it's a global change affecting links I'll leave it for someone with a robot to do... — Preceding unsigned comment added by 131.104.49.53 (talk) 15:37, 16 September 2005 (UTC)

dates
Could someone add the dates when ISO 646 and ISO 8859 became popular? — Preceding unsigned comment added by 12.30.114.67 (talk) 15:26, 20 July 2006 (UTC)

Who won the race?
During the 1960s, there was debate regarding whether character encoding standards [...] for computers should follow 1) existing practice in the telecommunications industry [...] or, conversely, 2) existing practice in the punched-card portion of the computer industry [...].

Well, who was the winner? --Abdull 20:21, 6 June 2007 (UTC)


 * EBCDIC is the descendent of punched-card codes, ASCII is a descendent of old Baudot-type codes, and pretty much everything else being used nowadays is a descendent of ASCII... AnonMoos 10:53, 14 September 2007 (UTC)

SSK
Who's SSK as mentioned in this article? --Abdull 20:21, 6 June 2007 (UTC)


 * Presumably some Scandinavian standards body not linked from the Wikipedia SSK disambiguation page. AnonMoos 10:57, 14 September 2007 (UTC)


 * SIS, Swedish Standards Institute, http://www.sis.se/, formerly Standardiseringskommissionen i Sverige (SSK). (The acronyms aren't 'linear', but the same goes for 'ISO'.) keka (talk) 09:14, 27 July 2009 (UTC)

Needs table
'nough said. Shinobu 17:58, 1 September 2007 (UTC)


 * Done. — Loadmaster (talk) 06:12, 8 February 2008 (UTC)

'IS' character set?
Does anyone know which character set 'IS' refers to in the table? --StuartBrady (Talk) 10:42, 14 September 2007 (UTC)


 * Presumably something for Icelandic... AnonMoos 10:54, 14 September 2007 (UTC)

Table incomplete
The table Characters for each ISO 646 compatible charset is incomplete. It only shows a few entries out of 128 possible. Is it that the missing entries are the same as ASCII? If so, that info is not in the article yet. Thanks. --Abdull (talk) 19:52, 7 February 2008 (UTC)


 * I added the full 128 code table. — Loadmaster (talk) 06:12, 8 February 2008 (UTC)

Combining characters
The red and white cells appear at random in the character table for combining characters. — Preceding unsigned comment added by 88.112.175.168 (talk) 11:35, 7 October 2011 (UTC)

rfc1345 observations
According to RFC1345 ISO646-KR differs from ISO646-US only in 0x5C position. 0x7E is '?. Same tilde symbol as ISO646-US

ISO646-CN, ISO646-GB and ISO646-SE have overline in 0x7E position and not tilde.

ISO646-US and ISO_646.irv:1991 are aliases.

ISO_646.irv:1983 has Cu in 0x24 position instead of $

In ISO646-HU 0x7E is U+02DD double acute accent and not tilde

Verifiability?
This article deals with ISO/IEC 646 which is a closed standard. ECMA-6 is an open standard published over internet.

Because ISO/IEC 646 is closed, it is not possible to verify what it contains. As ECMA-6 is publicly and freely available, it is more verifiable.

If verifiability import, and as both standards are very similar from each other, why not to have more focus on ECMA-6? — Preceding unsigned comment added by 86.75.160.141 (talk) 19:35, 8 October 2012 (UTC)


 * Apparently it wasn't as historically central, despite being more Internet-accessible during the last 10-15 years... AnonMoos (talk) 23:26, 10 October 2012 (UTC)

Circumflex accent in table
In the table "Characters for each ISO 646 compatible charset", comparing different versions of standard, the circumflex accent in ISO 646:1983 IRV on position 5E is given as corresponding to U+02C6 MODIFIER LETTER CIRCUMFLEX ACCENT. I thing, in the IRV version, the larger version of circumflex accent should be used; the U+005E CIRCUMFLEX ACCENT. — Preceding unsigned comment added by Jiri 1984 (talk • contribs) 14:37, 21 April 2013 (UTC)

National variants references?
I'm searching references for national variants cited in article. Where is the info about combining characters (red background)?--Unjoanqualsevol (talk) 19:33, 31 March 2014 (UTC)


 * Section 7 ("Composite Graphic Characters") of ECMA-6, for one... AnonMoos (talk) 06:38, 10 April 2014 (UTC)

US and IRV are identical yet not identical
In the article, it states that ISO/IEC 646-IRV is now identical to ASCII.

Yet in the table comparing all the different variants further down the page, ASCII (or 646-US) has 7E mapped as U+007E TILDE, while 646-IRV has it mapped as a different code point, U+02DC SMALL TILDE, which contradicts the above statement.

Then you have a similar deal with U+0027 APOSTROPHE and U+2019 RIGHT SINGLE QUOTATION MARK.

I would fix that myself, but many other entries in the same row also list the same U+02DC character, so are all of those wrong too? 58.173.133.147 (talk) 04:04, 10 May 2014 (UTC)

Code page 1022
I suspect it is the DEC Portuguese International Code page because there is no DEC Portuguese code page on the list, but IBM forgot to upload it!!! — Preceding unsigned comment added by Alexlatham96 (talk • contribs) 05:12, 21 February 2017 (UTC)
