Correct. It might work to use U+00A0 there if you want the vowel sign 
with no visible consonant:

     {\char"A0\char"1133E}

Alternatively, a workaround might be to look up the glyph ID with 
\XeTeXcharglyph and then print it using \XeTeXglyph, so something like:

     {\XeTeXglyph\XeTeXcharglyph"1133E}

should produce the desired glyph by itself.

(The spacing of these two options will be different, as the first uses 
no-break space as a base for the cluster, whereas the second just prints 
the vowel-sign glyph with no extra spacing.)
