// Make sure normalization is always on, and normalization flag is ignored.

// We need a character with two combining marks, from two different classes,
// to make ICU fail comparison without normalization (upper, lower accent).
// We will just switch order of combining characters to try to induce failure.

// FYI, this one wouldn't work, since both accents are from the same class:

// See http://demo.icu-project.org/icu-bin/nbrowser?t=&s=1E09&uv=0 and
