UTF-32 is an encoding that is identical to the unicode point as far as
I know. So what I am thinking is that one would either use the UTF-8
representation of the Unicode point as an index, or the unicode point
itself. Since using UTF-8 would not require any conversion (on UTF-8
locales) I think it would be preferrable.

The man page I read did not mention an anonymous map. I found an example
on Wikipedia though

anon = (char*)mmap(NULL, 4096, PROT_READ|PROT_WRITE,
                MAP_ANON|MAP_SHARED, -1, 0);

that probably means it may not be that portable after all. Thanks for
making me aware of it in any case.
