> I have been looking at the charset encoder/decoders for ebcdic (IBM1047) as a result
of HARMONY-6290 and I noticed that the character mappings appear to be slightly different
to those originally generated by the TableGenerator tool contributed as part of HARMONY-3593.
> When I run the tool on my local machine using the RI, I get byte 0x15 (NEL) mapped to
0x0A (unicode LF) and 0x25 (LF) mapped to 0x85 (unicode NEL). However the Harmony tables have
these values the other way around - i.e. byte 0x15 mapped to 0x85 and 0x25 mapped to 0x0A.
So it appears we currently have a character mapping difference to the RI.
> I am attaching a suggested patch.
