But, I don't accept that ASCII is only 7-bits and not 8-bits. My recollection is that ANSI X3.4-1986 defined *both* ASCII and extended ASCII. Of course, the last time I read that standard was over two decades ago ... So, AIR, extended ASCII are 8-bit characters with the high bit set. AIR, the extended ASCII character set was intended for platform specific, graphics, and math symbols. Rod Pemberton
