I'd like to get this point resolved.

...continuing, I wrote a script to (attempt to) exercise the various
character sets by writing all of the printable characters with each of
the selectable fonts, and changed my console-setup file to use ISO-8859-2
(both attached).
Currently I have via infocmp comparing linux2.2 to linux2.6:
comparing booleans.
comparing numbers.
comparing strings.
acsc:
'+\020\,\021-\030.^Y0\333`\004a\261f\370g\361h\260i\316j\331k\277l\332m\300n\305o~p\304q\304r\304s_t\303u\264v\301w\302x\263y\363z\362{\343|\330}\234~\376',
'++\,\,--..00__``aaffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}c~~'.
enacs: NULL, '\E(B\E)0'.
rmacs: '\E[10m', '^O'.
sgr:
'\E[0;10%?%p1%t;7%;%?%p2%t;4%;%?%p3%t;7%;%?%p4%t;5%;%?%p5%t;2%;%?%p6%t;1%;%?%p9%t;11%;m',
'\E[0;10%?%p1%t;7%;%?%p2%t;4%;%?%p3%t;7%;%?%p4%t;5%;%?%p5%t;2%;%?%p6%t;1%;m%?%p9%t\016%e\017%;'.
sgr0: '\E[0;10m', '\E[m\017'.
smacs: '\E[11m', '^N'.
and (perhaps someone can point out where I'm missing it), the only difference
I see (screenshots attached) is an odd glitch on the screen which seems to be
unrelated to what I'm trying to investigate.
