Sorry, yes, you are right. I didn't realize that.
Maybe because Lua 5.1 manual does not explain this conversion.

But now I have a question. Since Lua converts any type of newlines
into "\n" (in inclinenumber function), why does luaL_loadfilex opens
the script file in text mode ?
This adds complexity in the function since it has to reopen the file
in binary mode when the file is precompiled.
And there is (probably) a performance penalty since the new line
conversion is performed twice.
