Hello, I am comparing radical data for CJK characters from different sources, including the Unihan database. According to the Unihan documentation* the kRSUnicode radical should correspond to kRSKangXi radical, which in turn should be based on the Kang Xi dictionary.
Is there any explanation for the following discrepancies? Did I miss any other rules or reasoning behind the content of these two fields? Examples of the discrepancies: (1) A very common character for "most, maximum". U+6700 kRSKangXi 73.8 U+6700 kRSUnicode 13.10 (2) A funny character for autumn containing the turtle component. U+9F9D kRSKangXi 115.16 U+9F9D kRSKanWa 115.16 U+9F9D kRSUnicode 213.5 There are also characters that actually are not included in the Kang Xi dictionary**, but the Unihan data contain both a purported Kang Xi radical and in addition to that a _different_ Unicode radical. (3) The simplified turtle character (commonly assigned to the traditional radical #213): U+4E80 kRSKangXi 213.0 U+4E80 kRSUnicode 5.10 (4) Character with the radical #72/73 at the top, i.e. IMHO an arbitrary decision, but unexpectedly the fields differ: U+66FB kRSKangXi 72.7 U+66FB kRSUnicode 73.7 - - - [*] <http://www.unicode.org/reports/tr38/tr38-8.html>: "Property: kRSUnicode // Description: (...) The first value is intended to reflect the same radical as the kRSKangXi field and the stroke count of the glyph used to print the character within the Unicode Standard." [**] The two characters are missing from the '89 edition of Kang Xi (which should be the same as used for Unihan) according to search on this site: <http://ctext.org/dictionary.pl> -- Adam Nohejl _______________________________________________ Unicode mailing list Unicode@unicode.org http://unicode.org/mailman/listinfo/unicode
