Do we need active characters in that range at all for luatex (and
xetex)?  The UTF8 support (this is, the code that converts UTF-8 byte
sequences to Unicode LICR forms) in texinfo.tex should be simply
skipped since it is unnecessary.

Note that there is another bug: For 8bit engines, the glyphs for † and
‡ are taken from other fonts, but this substitution mechanism fails
for both luatex and xetex – a simple solution would be to use the CM
super fonts instead of 8bit Computer Modern.
