[kbd] [PATCH] Fix "compose as usual" for Unicode diacritics

[Michael Schutte <michi@uiae.at>]

struct ccc in compose_as_usua[() uses three char members of unspecified
signedness; in case the compiler decides that they should be signed,
negative integers will end up in the accent table for c3 > 127.

Avoid the problem by explicitly using unsigned chars.
