CCSID 6201 – LCS 3800-1 Extended – EBCDIC/5A

Explanation: Sadly, my only source for CPGID 2105's layout is the 120-character version (i.e. CCSID 2105), so I do not know for sure where the extra characters (documented by IBM as SM65 and SM07) are located, though I can make a fair educated guess that they're in the same locations as in CCSIDs 37 and 264 as applicable.
