{{ The Unicode Kangxi Radicals block Navbox }}

'''⾪''' is a Unicode character at '''U+2FAA''', named Kangxi Radical Slave. It is not a Chinese character in ordinary use. If you arrived here after copying a glyph out of a radical chart or a dictionary index, the character you almost certainly want is '''[[隶]]''' at U+96B6.

The two look identical in most fonts and mean the same thing, but they are separate code points, and software treats them as unrelated. A search for ⾪ will not find text containing 隶.

= What this code point is for =

Unicode encodes the 214 [[Kangxi radicals]] a second time, in a block of their own, so that a radical chart can be typeset as a chart. A table of radicals is a list of abstract indexing elements rather than a passage of text, and giving those elements their own code points lets a font apply chart-specific shapes and spacing without disturbing how the same glyph is drawn in running prose.

The block also serves round-trip compatibility with older East Asian character sets that had made the same separation.

Neither purpose involves writing words. ⾪ should not appear in article text, page titles, search queries, filenames, or any other place where the character [[隶]] is meant.

= Normalization behavior =

⾪ carries a '''compatibility''' decomposition to U+96B6. That determines exactly which normalization forms will convert it:

* '''NFKC''' and '''NFKD''' convert ⾪ to 隶
* '''NFC''' and '''NFD''' leave it unchanged

This is the practical trap. Compatibility decompositions are weaker than canonical ones, and most systems that normalize silently — file systems, database indexes, web forms — apply NFC rather than NFKC. So ⾪ survives in places where a canonically-decomposable character would have been folded, and two strings that look identical on screen compare as different.

The [[CJK Radicals Supplement]] block is worse in this respect. Of its 115 characters, only two carry any decomposition at all, so the remaining 113 will never normalize to anything under any form. A radical glyph copied from that block is permanently distinct from the character it depicts.
