I'm sorry. What happened?!

This makes no sense at all. Unicode does not define *any* glyphs for 
*any* characters, and never has. It maps abstract characters to code 
points. That's all. What glyph is used for those characters is a font 
choice. Unicode cannot change a glyph becuase it never assigned a glyph 
in the first place.

I suppose different printings of various books may use different fonts, 
but this is in no way normative.

Possibly, but none of this changes the fact that υ is the Greek 
small letter upsilon. I suppose you meant φ ? In Unicode that's 
the small Greek letter phi, whatever glyph is assigned.
