Hej Holger!   
      
    HG> didn't agree with the chr.codes I had   
      
   That is because it cannot be mapped out to PC8.  latin1 will work and will be   
   mapped out to 0xf8 (dec 248 if you prefer).  In both utf8 and latin1, decimal   
   148 is an extended control code and not whatever PC8 shows it as since PC8   
   doesn't have any extended control codes and instead has 8 bit characters for   
   that range (128-159).  Near as I can figure dec 148 in PC8 would be the "LATIN   
   SMALL LETTER O WITH DIAERESIS" which in latin1 is dec 246 or the ö character   
   in utf8.   
      
    HG> and the slashed capital O is to be found among the graphical chrs   
    HG> of PC8 as code 216. This is often used as a replacement for zero.   
      
   I'll have to take your word for that since I have never found a map for PC8.    
   I have seen specualtion that it is the same as CP437.  Is it?
