[XeTeX] how to suppress doted circle next to a glyph

[Michael Maxwell]

In my experience, a dotted circle is an indication that there's a 
non-base character which needs a base character before it, but there's 
no suitable base character.  If you type a Unicode Combining Acute 
Accent (U+0301), but there's no base character (like a vowel) preceding 
it, you'll get such a dotted circle.

If I'm not mistaken, U+1133E is the Grantha Vowel Sign Aa.  Maybe it 
needs a consonant to its left?
