The important part is the bit about "unaccented Latin letters". Without that clarification, "case-insensitive" in UTF-8 implies that the byte sequence "\xC7\xBC" compares equal to "\xC7\xBD" (i.e., 'Ǽ' == 'ǽ'), which is clearly not how that function works; and I'm ignoring fun issues with Unicode normalization forms. So yes, encoding does matter. -- Brane
