These come from xdvipdfmx, and are not related to the ICU library
update. If you get warnings like this (because of non-standard glyph
names for contextual glyphs, ligatures, etc.), it's likely that those
characters will not work properly in PDF text search, copy/paste,
etc.; apart from that, the output should be fine.
These warnings can be suppressed by using the option -qq (rather than
just -q) to xdvipdfmx. Maybe this should be the default that xetex uses?
