Shift_JIS to Unicode mapping

[Pulbere, Alexandru]

Hi,

I noticed that the Shift_JIS mapping table "ibm-943_P14A-2000" changed it's name to "ibm-943_P14A-1999" in ICU 2.6.
As well some of the mappings in this table changed.
For example Shift_JIS code point 0x8160 to map to Unicode 0xFF5E instead of 0x301C.
What was the reason for changing the mappings of these code points?
I know Microsoft Windows conversions don't recognize the Unicode code points ICU was mapping to before this change.

Thanks,
Alexandru Pulbere.

ibm-943_P14A-2000 wasn't really ibm-943_P14A-2000. All of the pre2.6
mapping tables had the year 2000 at the end due to the limitation of one
of our tools. I think the original mapping table was really
ibm-943_P14A-1998. Then the IBM CDRA updated ibm-943_P14A to match the
Windows behavior of Shift-JIS more closely in 1999.

So windows compatibility was the reason. Hope that helps.
