Well something like that. [DJW:] Actually it's 160 to 255, 128 to 159 (including 150) are "UNUSED". Also the ECMA standard looks fairly close to ISO 8859/1, if not identical, so the overall effect is (close to or) identical to limiting the maximum code to 255 and using ISO 10646. (The comments say ISO Latin/1 even if the formal reference is ECMA Latin 1.) From the 3.2 declaration: BASESET "ISO Registration Number 100//CHARSET ECMA-94 Right Part of Latin Alphabet Nr. 1//ESC 2/13 4/1" DESCSET 128 32 UNUSED 160 96 32 [DJW:] Only tab, LF, CR and the printable characters (32 to 126) are valid from ASCII. I'm not convinced that the last 32 is valid - I suspect it should be 160, as non-break space is code point 10/00, not 02/00 in the ECMA spec. (This could be a result of the ISO registration process, I suppose.) -- --------------------------- DISCLAIMER --------------------------------- Any views expressed in this message are those of the individual sender, except where the sender specifically states them to be the views of BTS. >
