I'll give one example more in detail:

Line 5444:
Codepoint is: 1F80 (GREEK SMALL LETTER ALPHA WITH PSILI AND YPOGEGRAMMENI)
Supposed Upperchar is: 1F88 (GREEK CAPITOL LETTER ALPHA WITH PSILI AND
YPOGEGRAMMENI)
ICU matches the Upperchar: 1F08 (GREEK CAPITOL LETTER ALPHA WITH PSILI )

So I think there might be something special with theses YPOGEGRAMMENI
because this is in any codepoint that causes trouble.

We checked with ICU v2.6.1 and ICU v2.8.0
