digitalmars.D - Solution to the encoding problem

Here is my "solution" to the encoding problem that a lot of people have been
complaining about. The problem is that d library functions cannot read or write
anything but unicode from stdin/stdout. So for fun I made:

http://folk.uio.no/mortennk/d/locale_v0.1.zip

Quick usage example:
















(The file also contains some general character conversion routines.)

Ok, it's not meant as a perfect solution, or even a good one. Just to
demonstrate _one_ way to solve the problem.

Oh, and it uses iconv and is currently linux-only. Sorry :) Any feedback is
appreciated.

Here is a more portable way of using iconv:
http://www.algonet.se/~afb/d/libiconv.d

Still, the iconv library is kinda huge ?

 968K    libiconv.2.dylib
 872K    iconv.dll


Even if it is built-in on most posix systems.

Good for the general case, but sorta overkill
for Latin-1 and other simple 8-bit encodings ?


And then I haven't even begun on locale... ;-)
(the code you posted uses GNU glibc version)

You see, the BSD locale.h has these instead:

 #define LC_ALL          0
 #define LC_COLLATE      1
 #define LC_CTYPE        2
 #define LC_MONETARY     3
 #define LC_NUMERIC      4
 #define LC_TIME         5
 #define LC_MESSAGES     6


And that's even more fun to port than the subtle
differences between GNU libiconv and BSD iconv...

Ah - cool! I had forgotten you had done that. Can we put the link in a FAQ 
somewhere? Together with a link to Mango's ICU port. Plus examples on how to 
use them.

By the way, how many FAQs do we have anyway? I see

Ben: Well I'd say we have at least 4 FAQs, if you add the following two:

DedicateD (http://int19h.tamb.ru/faq.html)
MKoD (my D site)(http://spottedtiger.tripod.com/D_Language/D_FAQ_XP.html)

I throw a bunch of hacks on my personal site,
that I don't really know where else to put...
(or didn't have the time to clean up for release)

I'll be happy to contribute some elsewhere ?
