If an implementation "uses" 8 bits for ASCII text (as opposed to hardware storage which is never less than 8 bits for a single C char, AFAIK), then it is not a valid ASCII implementation, i.e. does not interpret ASCII according to its definition. The whole point of specifying a format as 7 bits is that the 8th bit is ignored, or perhaps used in an implementation-defined manner, regardless of whether the 8th bit in a char is available or not. Once an encoding embraces 8 bits, it will be something like CP1252, ISO-8859-x, KOI-R, etc. Just not ASCII. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
