+Conformance to both @TeX{} and @sc{matlab} with respect to the @code{\circ}
+symbol is impossible.  While @TeX{} translates this symbol to @w{Unicode 2218}
+(U+2218), @sc{matlab} maps this to @w{Unicode 00B0} (U+00B0) instead.  Octave
+has chosen to follow the @TeX{} specification, but has added the additional
+symbol @code{\deg} which maps to the degree symbol (U+00B0).
