How I forgot that! internally, "Lucida Sans", "LucidaSans",
"lucidasans", "L U ci DaS anS" all are the same to luaotfload, we will
strip spaces and lower case font name before doing matching. So fontspec
can just strip the spaces in some way (if not easy in tex, can be done
in lua).
Well naturally stripping space is a solution which I already
mentioned at the begin of the thread. Nevertheless it is interesting
why it fails for luatex but not with xetex and I think I found the
reason: \fontname works differently.
In following example xetex returns the fontnames of the system fonts
surrounded by quotes ("Lucida Sans Regular", "Arial", but cmr10
without quotes) while luatex/luaoftload returns all fonts without
quotes: name:Lucida Sans. name:Arial. As during substituation
\fontname\font is feeded back to a font command luatex now looks due
to the missing quotes for the font name:Lucida
A simple solution would be to wrap the \fontname returned value in a {}
group before passing it back to \font.
