RE: windows-874 new registration

[McDonald Ira <imcdonald@sharplabs.com>]

Hi,

Tricky questions.

I agree with Martin that indicating the language/script
supported by a non-Unicode charset (such as Thai) is very
desirable.  I think this hint should be a strong SHOULD
in charset registrations/updates.

The issue of 'COMMON' versus 'LIMITED USE' is fuzzy.  

I'm slightly in favor of retaining (for now) 'COMMON' for 
the existing Windows code pages that are still the defaults 
in their respective countries/regions.  In those locales,
they ARE in fact currently in common usage.

Cheers,
- Ira

Trying to address the entire thread: :)

I like that.

> For such more or less obsolete charsets, why do you write COMMON ?

IMO *any* code page is less preferable to UTF-8/UTF-16.  So in that sense, this is as "common" as any of the other registered code pages should be.  In particular for Thai machines it is the default system code page for the machine, so ANSI apps will use it, so in that sense it is common in a Thai environment.

> UTF-8 is preferred to windows-1252 when permissible.

I'd be happy to say that since I think UTF-8 is a better solution and since Windows is effectively a Microsoft code page.

> UTF-8 is preferred to ISO-8859-1 when permissible.

Although I agree, I wouldn't presume to change the definition for an ISO code page.  I'd recommend that separately (like in my blog).
