I must correct you - ASCII is a 7-bit encoding

The 8th bit is padding. Many mail gateways still strip the 8th bit. The world wide email system is still only 7 bit safe. All other bits are passed through this ugly old pipe by representing non-ascii using ascii via mechanisms like base64 and entities.

At least, this was true 5 years ago when I last investigated the problem in detail.

What the heck is text? - (systems) - (56) - March 12, 2005, 11:48:38 AM EST

It depends on the context. - (Another Scott) - (2) - March 12, 2005, 12:23:39 PM EST

Re: Unicode and ASCII - Nitpick II - (jb4) - March 25, 2005, 01:40:46 PM EST

you are confusing text with display - (boxley) - (12) - March 12, 2005, 06:53:13 PM EST

Uhhh..Not quite, Bill - (jb4) - (11) - March 25, 2005, 01:50:46 PM EST

And that is one thing that sucks about Unicode - (ben_tilly) - (9) - March 25, 2005, 03:09:44 PM EST

At least they're consistent - (jb4) - (8) - March 25, 2005, 06:02:42 PM EST

But it is a problem - (ben_tilly) - March 25, 2005, 06:13:17 PM EST

Except for that full width/half width ascii thing - (tuberculosis) - (5) - March 27, 2005, 09:40:24 PM EST

I dunno... - (jb4) - March 28, 2005, 12:11:15 PM EST

My personal take on it - (jake123) - (3) - March 28, 2005, 12:15:20 PM EST

Perhaps, but it makes searching tricky - (tuberculosis) - (2) - March 28, 2005, 02:49:36 PM EST

Well, if it was an easy problem - (jake123) - March 28, 2005, 03:29:43 PM EST

Have you all seen the HUGE unicode poster? - (FuManChu) - March 28, 2005, 04:33:12 PM EST

close enough to debug a table entry :-) - (boxley) - March 26, 2005, 09:26:51 AM EST

Text is not as simple as it seems - (ben_tilly) - March 12, 2005, 11:00:34 PM EST

This is one thing that Java handles pretty well - (bluke) - March 13, 2005, 11:35:09 AM EST

Rule #1 - Everything you think you know is wrong - (tuberculosis) - (29) - Aug. 21, 2007, 06:28:08 AM EDT

Why xenophobic? - (drewk) - (28) - March 14, 2005, 10:44:16 AM EST

Because they didn't think... - (pwhysall) - March 14, 2005, 11:24:31 AM EST

Because if they had spent any time at all - (tuberculosis) - (25) - Aug. 21, 2007, 06:30:01 AM EDT

Now how about addressing my example - (drewk) - (17) - March 14, 2005, 12:13:47 PM EST

The best explanation that I've seen of why 2 digits... - (ben_tilly) - March 14, 2005, 12:46:32 PM EST

No, but they were xenophobic etc - (jake123) - (15) - March 14, 2005, 02:50:01 PM EST

xenophobic's probably the wrong word - (SpiceWare) - (14) - March 14, 2005, 04:12:18 PM EST

Yeah, you're right - (jake123) - (13) - March 14, 2005, 05:02:32 PM EST

How about "escessively humble"? - (drewk) - (4) - March 14, 2005, 05:35:25 PM EST

Look, the point about the two digits for a year is well - (jake123) - (1) - March 14, 2005, 06:09:09 PM EST

Disagree - (jb4) - March 25, 2005, 02:15:41 PM EST

Maybe... - (tuberculosis) - (1) - Aug. 21, 2007, 06:31:43 AM EDT

How about simply "provincial". - (a6l6e6x) - March 14, 2005, 08:02:42 PM EST

The people who coded for teletypes and green terminals - (Arkadiy) - (7) - March 14, 2005, 05:37:55 PM EST

Internationalization would not have been so easy - (ben_tilly) - March 14, 2005, 07:23:05 PM EST

Text layout in 80 by 24 grid of monspaced font? - (Arkadiy) - (1) - March 14, 2005, 07:59:49 PM EST

Phone books back then - (jake123) - March 15, 2005, 11:18:10 AM EST

Please don't use the letter "e" in your code. - (pwhysall) - (2) - March 14, 2005, 06:20:45 PM EST

I certainly used to do without "e" - (Arkadiy) - March 14, 2005, 08:01:39 PM EST

I couldn't use "e" either ... - (JimWeirich) - March 15, 2005, 05:52:09 PM EST

Oh, come ON already - (jb4) - (6) - March 25, 2005, 02:20:51 PM EST
