Xunicode points the \textcelsius macro at a single character, ℃;
viz.
   \DeclareUTFcharacter[\UTFencname]{x2103}{\textcelsius}

Some fonts might not support this.
On my machine  Times New Roman  does not.

So you could try cancelling it using:

    \UndeclareUTFcharacter[\UTFencname]{x2103}{\textcelsius}

Put this in your preamble, after Xunicode has been loaded.
Now the  \textcelsius  macro should revert to something
which builds the symbol from 2 pieces.  (Or maybe not.)
Please give it a try.

If this does not work for you, please send a complete
test file, cut down as much as possible but displaying
the problem. In particular, we need to see how you are
using the \textcelsius  command; e.g., in math-mode
or directly in a paragraph or line of text, which may be
affecting which is being used.
