The actual cause of the processing problems we have been seeing are the
character set definitions in the SGML declarations of the respective
document types.

For DocBook SGML 4.2:

CHARSET

BASESET
"ISO 646:1983//CHARSET International Reference Version (IRV)//ESC 2/5 4/0"
DESCSET
0 9 UNUSED
9 2 9
11 2 UNUSED
13 1 13
14 18 UNUSED
32 95 32
127 1 UNUSED

BASESET
"ISO Registration Number 100//CHARSET ECMA-94 Right Part of Latin Alphabet Nr. 1//ESC 2/13 4/1"
DESCSET
128 32 UNUSED
160 96 32

For XML:

CHARSET
BASESET
"ISO Registration Number 177//CHARSET
ISO/IEC 10646-1:1993 UCS-4 with implementation
level 3//ESC 2/5 2/15 4/6"
DESCSET
0 9 UNUSED
9 2 9
11 2 UNUSED
13 1 13
14 18 UNUSED
32 95 32
127 1 UNUSED
128 32 UNUSED
160 55136 160
55296 2048 UNUSED -- surrogates --
57344 8190 57344
65534 2 UNUSED -- FFFE and FFFF --
65536 1048576 65536 -- 16 planes outside BMP --
