-lc(), uc(), lcfirst(), and ucfirst() work only for some of the
-simplest cases, where the mapping goes from a single Unicode character
-to another single Unicode character.  See lib/unicore/SpecCase.txt
-(and CaseFold.txt).
+Mostly implemented (all of 1:1, 1:N, N:1), only the "final sigma"
+and locale-specific rules of SpecCase are not implemented.
