This document describes the U-source ideographs in the Unicode standard.
This is a draft document which may be updated, replaced, or superseded by other documents at any time. Publication does not imply endorsement by the Unicode Consortium. This is not a stable document; it is inappropriate to cite this document as other than a work in progress.
A Unicode Technical Report (UTR) contains informative material. Conformance to the Unicode Standard does not imply conformance to any UTR. Other specifications, however, are free to make normative references to a UTR.
Please submit corrigenda and other comments with the online reporting form [Feedback]. Related information that is useful in understanding this document is found in References.

This documents describes U-source ideographs as used by the Ideographic Rapporteur Group (IRG) in its Han unification work. The IRG consists of experts representing all the East Asian nations using ideographs in their writing and is the international standards body that does the actual unification work for Han.
The U-source consists of the CJK ideographs which have been submitted to the UTC as potential candidates for encoding. Not all of these are, in fact, suitable candidates for encoding, and their inclusion in this document should not be taken as approval for their encoding on the part of the UTC.
The actual U-source data are found in two additional files:
The status field reflects the ideograph's current status. The value of this field can change over time. The possible values are C, D, U, V, W, and X.
A status of C means that the ideograph is found in Extension C. This is currently under ballot in WG2.
A status of D means that the ideograph has been submitted to the IRG as part of the UTC's Extension D proposal.
A status of U means that the ideograph is already encoded in Unicode. Characters with a status of U were either added to the U-source database in error, or are characters encoded in Unicode before the IRG began its work.
A status of V means that the ideograph is a variant of a character encoded in Unicode. These variants are not limited to Z-variants. Other variants include glyphs with components rearranged (e.g., UTC00344, which rearranges the components of U+69AB but is pronounced the same and means the same), simplified versions of encoded characters (e.g., UTC00842), and ideographs which mean the same and are pronounced the same as encoded ideographs and have a sufficiently similar shape as to be easily mistaken for one another (e.g., UTC00399). This is a deliberately less strict, if somewhat more subjective, standard than is used for unification work.
A status of W means that the ideograph is not suitable for encoding. An example here is UTC00118, which is used as a decoration in the novels Xenocide and Children of the Mind by Orson Scott Card. While the character does have an apparent intended meaning (something like "monster-killer"), it isn't suitable for encoding because of its ad hoc, nonce nature and lake of generalized use outside of the context of two specific English-language novels. The bulk of the characters with a status of W are Wenlin-specific Z-variants which should be represented (if at all), via a variation sequence defined by Wenlin, not by the UTC.
Finally a status of X means the ideograph is a candate for inclusion in an encoding proposal post-dating Extension D.
The source field consists of source information, which generally consists of a source tag usually followed by a source-specific index string. Source tags and indices are separated by a space, and multiple source indices are separated by commas. Multiple sources are separated by asterisks.
The source tag may be a URI, in which case the index string is the date (year-month-date) when the URI was accessed. The source tag may also be a U-source index for cases where an ideograph was added to the U-source twice. The source tags beginnig with a lower-case k correspond to fields within the Unihan database. Please consult [UAX38] for information on these sources and the format and meaning of the index strings.
