I just realised that this grammar is ambiguous, because LC is a subset of 
L, so should be replaced by two tests:


================


input: char*.

-char: C; L; M; N; P; S; Z; Unassigned.
Unassigned: ~[C; L; M; N; P; S; Z].

C: [C].
L: [L].
M: [M].
N: [N].
P: [P].
S: [S].
Z: [Z].


===================
input: char*.

-char: C; L; LC; Lm ; Lo; M; N; P; S; Z; Unassigned.
Unassigned: ~[C; L; LC; Lm ; Lo; M; N; P; S; Z].

C: [C].
L: [L].
LC: [LC].
Lm: [Lm].
Lo: [Lo].
M: [M].
N: [N].
P: [P].
S: [S].
Z: [Z].
