Ah, then I think that \377 string is to record safely encodable character sets for each coding system. If Nth element is not \377, the charset whose ID is N is encodable by that coding system. And, yes, those strings can be in pure memory when created by temacs. But, note that one can change a definition of a coding system at runtime (perhaps rarely happen) and it makes the string in pure memory accessed from nowhere. --- Kenichi Handa handa@m17n.org
