LuaFileSystem on Windows and character sets

[Tuomo Valkonen <tuomov@...>]

Is there some way to make LuaFileSystem to use UTF-8 on
Windows? Currently it seems to use some character set
(winlatin1?) that can not represent all the characters
in use: string.len of lfs.dir results equals the length
of the string printed on the console, which is full of
question marks for characters not covered by a single
byte. So the results of lfs.dir seem to be full of
non-existent files.
