Oh, I think I see it. "ά" is:
1F71;GREEK SMALL LETTER ALPHA WITH OXIA;Ll;0;L;03AC;;;;N;;;1FBB;;1FBB
The Python script is looking for combining sequences that add accents,
but this one has just "03AC" in the combining sequence field, so it's
a kind of "simple" redirection that points here:
03AC;GREEK SMALL LETTER ALPHA WITH TONOS;Ll;0;L;03B1 0301;;;;N;GREEK
SMALL LETTER ALPHA TONOS;;0386;;0386
That has a normal looking sequence that we can understand (α + an
accent). If I tell the script to follow such "simple" redirections, I
get over a thousand new mappings, including those. See attached.
There is probably more correct terminology that I'm using here...
