Note on Printed CJK Code Charts

The increasing size of the Unicode Standard poses special problems in creating a book publication. For the last several versions, size considerations have required putting portions of the standard on the CD-ROM attached to the book's back cover, instead of printing everything.

After lengthy discussions with our publisher, it became clear that continuing to provide the full printed code charts for the large sets of CJK ideographs and Hangul syllables would have made it impossible to offer the standard at a reasonable price or in a single volume.

On the positive side, for the first time the entire text of the standard is available on paper, including the Unicode Standard Annexes. Previously, such crucial specifications as Normalization, Linebreaking and the Bidirectional Algorithm were available only on the CD-ROM.

The CJK code charts, of course, remain an integral part of the Standard. They are still included in every copy of The Unicode Standard, 5.0, as electronic copy on the CD-ROM attached to the book's back cover.

The consortium is exploring ways to make the CJK charts available in printed form as a separate publication using on-demand publishing. The long term plans include updating that publication in the future to make it even more useful for CJK users than the CJK code charts used in Unicode 4.0.

The following list gives the name and code point range of all CJK tables affected, together with a link to the online version of these code charts. For the ideographs, there is also an online database available that contains information beyond what is available in the charts.
