osd_libass: fix \n escapes

Browse Source 
Apparently libass can't be made to not interpret "\n" as escape. That
means "\n" can't be printed literally. Use the same hack that was added
to mplayer2 when that project merged osd_libass.c: add an invisible
zero-width joiner character between "\" and "n". It seems U+FEFF is
deprecated, because it has been redefined as BOM mark. Use U+2060, which
seems to be the replacement.
