Assuming the OP is interested in "native" truetype/opentype fonts, not
.tfm-based fonts, \XeTeXcharglyph is the simple answer.

As I normally use (Linux Libertine O or TeX Gyre Pagella), Linux
Biolinum O and Asana Math, I'm interested i "native" opentype fonts.
\XeTeXcharglyph (and Heiko's code) work in text mode. But I also print
SI values in math mode, where it doesn't work. See the minimal example:
\documentclass{minimal}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{DejaVu Serif}
\setmathfont{XITS Math}
\usepackage{siunitx}
\sisetup{%
detect-all,
}
\usepackage{pgffor}
\begin{document}
\sisetup{%
text-celsius=9
}
\foreach \phont in {TeX Gyre Pagella, Linux Libertine O, DejaVu Serif}
{
\setmainfont{\phont}
\ifnum\XeTeXfonttype\font>0
7
\ifnum\XeTeXcharglyph"2103>0
8
\sisetup{text-celsius=℃}\SI{123}{\celsius}
\fi
\fi
\SI{456}{\celsius}\\
}
\sisetup{%
math-celsius=9
}
\foreach \phont in {Asana Math, XITS Math, STIXGeneral, Neo Euler}
{
\setmathfont{\phont}
\(\ifnum\XeTeXfonttype\font>0
7
\ifnum\XeTeXcharglyph"2103>0
8
\sisetup{math-celsius=℃}\SI{123}{\celsius}
\fi
\fi\)
\(\SI{456}{\celsius}\)\\
}
\end{document}
Although u2103 (why did Heiko use u018e=latin capital reversed E?) is
only available in Asana Math (which on the other hand doesn't have °)
the innermost \if yields true (can be seen by printing the 8 and setting
math-celsius to a not-defined glyph).
Another problem (but that might be due to siunitx): the following
\SI{456}{\celsius} doesn't know about the \sisetup in the math before. I
assume this has something to do with grouping and local/global changes.
But how can I check for glyph availability in math fonts whithout going
into math mode via \(\)?
Thanks
Toscho
