That concerned me, as well. I have confirmed the lines are not empty. If
you open the file in a text editor (I'm using KDE's Kate), and insert a
standard character at the beginning of one of those lines, the diacritic
then appears, combined with the character you just entered. The only
program I've found that wants to display them on their own is vi (and I
only just thought of trying that).
From what I can tell, this is likely a font issue:
