Interesting. This is the first thing I thought, but when I fed "lazy" into google, it happily accepted and displayed the results, so I thought there might be something else. But teh text editors that I tried indeed don't match the characters when I search them.
google is using unicode equivalence[1] to remap back to "standard" latin characters. this is important because, e.g., professional type-setting software may replace two adjacent "f" characters with a double-F ligature "ff" depending on kerning. without unicode equivalence, google would fail on a lot of copy-paste queries.
