If fontconfig does not find an exact match, it tries different rules
to find a replacement font. It may happen that it finds the required
font if only case does not match. It also depends how xetex and luatex
cooperate with fontconfig. And this may chage after OS upgrade. If I
am not sure, I always try "fc-match -v <fontname>" in order to find,
under which name the system's  fontconfig knows the font.
