      This code fails on 64-bit Windows platforms, and with ICU:

      const QString lhs(qsizetype(INT_MAX) + 1, u'A');
const QString rhs = lhs + u'A';
assert(QString::localeAwareCompare(lhs, rhs) < 0);

      The APIs we use don't support more than INT_MAX characters (CompareStringsEx, QCollator).
