[edit] Language...

can someone put this in english for the common man? —Preceding unsigned comment added by 75.108.224.182 (talk) 05:22, 25 February 2008 (UTC)

Sure, just take a look at Evil. Jpatokal (talk) 09:57, 25 February 2008 (UTC)

[edit] Typo?

developed by a Japanese company called ASCII

Sounds like a typo, but I don't know if it is. First google page doesn't seem show anything. JamesBrownJr 22:17, 4 May 2006 (UTC)

It's not: the company is for real. Jpatokal 02:03, 5 May 2006 (UTC)


Ken Lunde states on page 175 of his authoritative book "CJKV Information Processing", O'Reilly & Associates, 1999, ISBN 1565922247, that shift-JIS was "originally developed by Microsoft Corporation". Later on page 176 he makes a reference to the ASCII Corporation's version of Japanese TEX as one of four examples of computer platforms or environments that uses shift-jis internally.
Lunde at least does not seem to be crediting the ASCII Corporation with having invented shift-jis. Morten Johnsen 23:51, 25 June 2006 (UTC)

The article has an underscore in the title which appears nowhere else in the article. Is this correct or a typo? If it's correct, it should be used throughout. User:Fredhoysted 14:57 (UTC)

Underscores are not used in normal English. However, MIME names cannot contain spaces; this is a common restriction for identifiers in software, it is also seen in programming languages for example. So to substitute an underscore is used in the MIME name. Shinobu 05:23, 4 November 2007 (UTC)

[edit] Umlauts

Why has Shift-JIS no code points for umlauts assigned? --84.61.71.163 15:25, 15 May 2006 (UTC)

Japanese typers rarely have a need to type the words "Mötley Crüe". You could use ISO-2022-JP-2, which has a mechanism to switch to ISO-8859-1 (includes umlauts), but you might as well just use UTF-8. --150.216.151.171 17:59, 9 July 2006 (UTC)


[edit] Upper and Lower ASCII

This page uses the term "upper ASCII" and "lower ASCII". I believe that the writer meant "characters > 127" and "characters <= 127" in a fixed-width 8-bit encoding. But ASCII only defines 127 characters. There is no "upper ASCII".

[edit] Browser interpretation of 0x5C

At least Firefox interprets 0x5C in Shift_JIS as '\' and not '¥'. I suspect this is because the '\' character is used to escape characters in Javascript, so having an encoding without a representation of that character would be a security problem. JeffreyYasskin 21:20, 19 December 2006 (UTC)

And you would be wrong to suspect that. 0x5c is commonly used as a special character, regardless of what symbol that character value actually represents. So on a Japanese computer you have filesystem paths like "C:¥Program Files¥", the DOS prompt looks like "C:¥>" and a Hello World program might contain the line 'cout << "Hello World!¥n";'.

[edit] ASCII coporation: not a typo

Hi, I wrote a large portion of this article (before I had a sign-in) and that is what I meant when I wrote it. Sadly I could not remember where I read it, but I've done some googling so I'll add a link that backs up what I said. —The preceding unsigned comment was added by Tim Band (talk • contribs) 15:38, 7 May 2007 (UTC).

[edit]  :1997 - what does that mean?

JIS X 0201:1997 (for the single-byte characters) and JIS X 0208:1997 (for the double byte characters)

What does :1997 mean? The linked articles don't yield a clue, and both state that the standards were set in 1969 and 1990(?). Were they revised in 1997? If so, why didn't they simply get a new four-digit number? Shinobu 16:16, 31 August 2007 (UTC)

1969 and 1983, yes; AFAIK there are no later revisions. The one you're thinking of in 1990 is JIS-X-0212 Tacitus Prime 11:22, 11 September 2007 (UTC)

So the ":1997"'s in the article are wrong and should go, right? Shinobu 05:32, 4 November 2007 (UTC)

[edit] EUC-JP

The article says "the competing 8-bit format EUC-JP, which does not support halfwidth katakana" - but EUC does indeed have the halfwidth katakana (upper half of JIS-X-0201:1976) in G2 (i.e., as two-byte sequences 0x8E 0xA1 .. 0x8E 0xDF) Tacitus Prime 11:22, 11 September 2007 (UTC)

The article means that it doesn't support single-byte encoding of halfwidth katakana. I've added a clarification. Jpatokal 12:53, 11 September 2007 (UTC)
