I'm not sure whether people are using "canonicalize" in the generic sense or if they mean canonical mappings as defined by the Unicode standard. Just to be clear, the initial issue raised about U+00B5 MICRO SIGN versus U+03BC GREEK SMALL LETTER MU would not be fixed by a canonical decomposition. However, U+00B5 does have a compatibility decomposition to U+03BC.
The official definitions are given in http://www.unicode.org/versions/Unicode6.2.0/ch03.pdf, and some relevant suggestions about handling identifiers in the context of Unicode are in http://www.unicode.org/versions/Unicode6.2.0/ch03.pdf.
