If you want static data on this, then the various sites with mapping tables are a good source.
If you want this at runtime, ICU 2.6 will have an API ucnv_getUnicodeSet() that gives you a set of
all Unicode code points that the specified ICU converter roundtrips. (It's fully implemented in the
current CVS snapshot.)
Of course, this is based on the particular mapping table that is loaded for the converter (mostly
IBM tables in the default build), but you can build your own tables into ICU if you like.
For an online example, see the ICU Converter Explorer at http://oss.software.ibm.com/icu/demo/
-> select a converter name, then on the new page click "View Complete Set..."

ICU has its UnicodeSet C++/Java class for all kinds of sets of code points...
(The above C API fills a C USet which is a thin C wrapper around C++ UnicodeSet.)
