These are not CMap resources, but they indeed use CMap syntax. It is  
thus easy to confuse them with genuine CMap resources. A genuine CMap  
resource maps character codes to CIDs in a unidirectional manner.

Some of the files you mentioned, such as Adobe-GB1-UCS2, are ToUnicode  
mapping files, which unidirectionally map CIDs to UTF-16 character  
codes. The others map between character codes, or have other  
specialized purposes for Acrobat or Distiller.

I maintain all CMap resources at Adobe Systems, and although the  
Acrobat team manages the ToUnicode mapping files, I am the one who  
maintains them. Almost all of the other Acrobat-specific mapping files  
(that use CMap syntax) have not changed for years. If memory serves,  
most were introduced during Acrobat 4.0 development, and haven't  
changed since then.

If these Acrobat-specific mapping files are to be placed under the  
same open source license, I will need to work with the Acrobat  
development team. I would prefer that they be included in a separate  
open source project.

Karl,

I discussed this with the Acrobat team today, and putting the Acrobat  
mapping files under the same open source license sees very favorable.  
If I can make it happen, it may take until the end of October for the  
open source project to go live. I am less then a week away from my  
annual pronghorn antelope hunt, which involves driving from California  
to Wyoming, and after that I am attending IUC33. See:

   http://www.unicodeconference.org/

I am giving two presentations, and just started working on them.

In any case, I will keep you posted.

Regards...

Hi Ken,

   > GBK-EUC-UCS2, Adobe-GB1-UCS2, GBpc-EUC-UCS2, etc. Are they  

    If these Acrobat-specific mapping files are to be placed under the  
    same open source license, 

That would be very desirable.

    I will need to work with the Acrobat development team. I would
    prefer that they be included in a separate open source project.

However it works best for you.

We greatly appreciate all your efforts!

Thanks,
Karl

Nice :-)

In the poppler[1] project we also would also like to see files like Adobe-
Japan1-UCS2 be released under a free license since we use them. I think they 
are part of those "Acrobat mapping files" you mention, but just to be sure.

Thanks for the effort,

This is one of the benefits of both working at Adobe Systems and  
having Acrobat's ear. ;-)

The Adobe-{CNS1,GB1,Japan1,Korea1}-UCS2 files are the "ToUnicode"  
mapping files, and are among the Acrobat mapping files that we are  
discussing. They are a special case of the Acrobat mapping files in  
that they specifically map CIDs to character codes, specifically  
UTF-16BE, in a unidirectional manner.

How is the open sourcing of Adobe-Japan1-UCS2, GBK-EUC-UCS2, Adobe-GB1-UCS2, 
GBpc-EUC-UCS2, etc. progressing?

Albert,

Your email is *very* timely, because it was on Friday (11/13/2009)  
that the Acrobat team gave the proverbial "green light" to open-source  
these mapping resources.

Anyway, I plan to spend the better part of the coming week preparing  
the files, which primarily amounts to adding the open source license  
to the headers of each file. The tentative name of the open source  
project is "Mapping Resources for PDF."

BTW, you might find the following forum thread to be helpful:

With best regards...

All,

I have some very good news to share. The "Mapping Resources for PDF" open source project, which includes all of the CMap-like mapping resources, went public today. See:

  http://opensource.adobe.com/wiki/display/pdfmapping/Mapping+Resources+for+PDF

Enjoy!
