A submission to the Unicode Consortium’s Ideographic [sic] Variation Database for the “Combined registration of the Adobe-Japan1 collection and of sequences in that collection” is available for review through November 25. This submission, PRI 108, is a revision of PRI 98.
This set “enumerates 23,058 glyphs” and contains 14,664 tetragraphs (Chinese characters / kanji). About three quarters of Unicode pertains to Chinese characters.
Two sets of charts are available: the complete one (4.4 MB PDF), which shows all the submitted sequences, and the partial one (776 KB PDF), which shows “only the characters for which multiple sequences are submitted.”
Below is a more or less random sample of some of the tetragraphs.
Initially I was going to combine this announcement with a rant against Unicode’s continued misuse of the term “ideographic.” But I’ve decided to save that for a separate post.
