Jython: Upper-ASCII characters '\351' from chr(233)

[Maurice Bauhahn]

Thank you very much for your persistent help.

I was able to get the 8th bit characters to act as keys...with a somewhat
complex construction: chr(int(linesplit[0])). Linesplit had decimal
numbers in text format.

linesplit = split('\t',encodingline)
         if (len(linesplit) > 5):
            try:
               templist = linesplit[2:4]
               templist.append(split(';|:',linesplit[4]))
               templist.append(strip(linesplit[5]))
               encodedict[chr(int(linesplit[0]))] = templist
               print templist
            except ValueError:
               logerror('My error', linesplit[0])
         else:
            logerror('Not >5 fields long', linesplit)
