I've explicitly mentioned in my first mail that I've removed
everything related to luatex from `.texlive2013'...

The problem wasn't unreadable fonts. It's rather the fact that
luaotfload is apparently not able to handle old Chinese fonts, for
example `avkv.ttf'. This font has an invalid PostScript font name
`全真楷書^P' (the ^P is a control character), and I guess this is
the very problem. Moving away the directory with those fonts, the
call succeeds. Additionally, this font has a `OS/2' table with
version 0, which is unusual also, together with more peculiarities.
Who is responsible for this program? Neither --version nor --help
gives any contact (which is also a bug IMHO). Since my lua knowledge
is zero, I can't debug this by myself.
 According to the specs, only characters from a special ASCII
subset are allowed.
