FSVO "same".  We're talking different languages.  So in IBM-273
"A" is 'C1'x.  In ISO8859-1, "A" is '41'x,  So, the same characters
but at different code points.  The tagging matters.

Yes, apparently IBM-273 and ISO8859-1 encode the same graphemes
at different code points.

Why are there multiple CECPs?  It seems any one would suffice.
