[XeTeX] Unaligned combining diacritic

It's a font issue. Unless a font maker specifically sets up each combining
mark to fit correctly over all the possible base characters through the
OpenType mark to base feature, they won't work right. A partial exception
might be a monospaced font; since all the characters are the same width,
things will work better than in a proportionally spaced font. But even in a
monspaced font, you won't get perfection without some manual adjustments on
the font maker's part; e.g., an acute or grave that is mathematically
centered over a character probably won't look right, and there is also the
need to replace a dotted i with the dotless version before applying accents.
Junicode is one open-source font that does support combining marks well, if
you need to use them. Charis SIL is another.
