ISO 15924

The Unicode Consortium has been designated as Registration Authority 
for ISO 15924; I have been engaged by the Consortium to act as 
Registrar.

The ISO 15924 web site is now online at http://www.unicode.org/iso15924/

The Registrar requests that the e-mail list iso15924 <at> dkuug.dk be 
discontinued, with thanks to Keld Simonsen and DKUUG for making it 
available as the standard was developed. Discussion of ISO 15924 
matters should take place on the general unicode <at> unicode.org list.

As originator and editor of this standard, I would like to thank 
everyone who participated in its development, and trust that it will 
be a useful standard for our work.

One bug in the new ISO 15924 database:
The downloadable list in plain text:
http://www.unicode.org/iso15924/iso15924-en.zip
is encoded with occurences of named character references instead of plain UTF-8.
This occurs in the "ID" column, where there are some occurences of "&nbsp;"
(which are spurious here and should be removed).
This breaks the CSV format where a semicolon is a field separator...

The FDIS from February 2003 states that "The four-letter codes SHALL be
written with an initial capital Latin letter and final small Latin
letters" (emphasis mine).

Although this is a useful convention and aids readability, I would
suggest -- without any authority -- that it is only a convention and not
an absolute requirement for use of the codes, just as the analogous
conventions to express ISO 639 and ISO 3166 codes in all-lowercase and
all-uppercase, respectively, are just conventions.

In particular, both RFC 3066 and its (in-progress) successor state that
language tags and subtags "are to be treated as case insensitive."  And,
with apologies for bringing up a sore point for many, Unicode recommends
converting all language tags, including subtags, to lowercase before
encoding them as Plane 14 language tag characters (TUS 4.0, section
15.10, page 405).

ISO 15924 alpha-4 codes are already distinguishable from ISO 639 and ISO
3166 codes, simply by virtue of being four letters long.

Michael, please let me know if I am off base on this.

Never mind that; the *actual approved standard* says the same:

http://www.unicode.org/iso15924/standard/index.html

I was thinking about earlier debates as to whether ISO would allow the
standard to be published online, for free, and didn't think to check
whether it was available at unicode.org.

Re: ISO 15924

Michael,

This is welcome news and congratulations.

The web page says:
"Additions to the ISO 15924 codes for scripts will be announced on the Unicode
discussion list. Discussion about ISO 15924 and script codes is welcome on this
list. "

Although I have no objections to announcements and discussion additionally on
the Unicode list, can I respectfully suggest there should also be a list
dedicated to 15924, so that people looking for announcements etc specific to
ISO 15924, won't miss them in the other Unicode traffic?

I understand that there is overlap if there are 2 lists. If a separate
discussion list is undersirable, then at least a separate list just for
announcements, seems called for. (And the announcements can be made to more
than one list, as was done in this case.)

RE: ISO 15924

I have the same concern.  Owing to time pressure, I am no 
longer on the unicode list and so hope that ISO 15924 
announcements will be made on ietf-languages <at> iana.org too.

Thanks,
Misha

In the code lists at http://www.unicode.org/iso15924/iso15924-codes.html the 4-letter 
script codes are shown capitalised, e.g. Arab not arab, Armn not armn, etc.. Is this 
intentional? Should the codes always be capitalised? Does it matter if they are not?

John,

I remember having a discussion about 4 years ago this about, regarding an
item of conflict between ISO 15924 (then pretty advanced) and a new code
list used for a similar use in Microsoft's and Adobe's proprietary
"OpenType". I am not 100% sure, but I even record you might be instrumental
in the design of this second list.

If I remember correctly, a good part of these lists were merged, which is
certainly a good thing, since we do not have any need for two concurrent
lists. In fact, I believed the intent on both parts was to merge. On its
part, ISO 15924 did change the codes it had for everything that were in use,
even including the Indian OpenType support which was still in infancy but
was shiping as part of IE5.

But then there was the point about capitalization. Following previous use in
Apple resources then TrueType, Microsoft designed its codes in all lower
case (which with Apple was reserved for the non-private specifications).

Re: ISO 15924

Michael Everson's tremendous personal contribution to the development of ISO 15924 is to be commended.  I
think it is very fitting that he act as registrar and I am sure he will excel in that duty as well.
