    • 5.10.0 Alpha, 5.15.3, 6.0.0

    Description

      Example:
         

          const QString str1 = QStringLiteral("String A");
    const QString str2 = QStringLiteral("String A");
    const QString str3 = QStringLiteral("string A");
    const QString str4 = QStringLiteral("string B");
    const QString str5 = QStringLiteral("String B");

    qDebug() << "1 vs. 2: " << str1.localeAwareCompare(str2); //  0, result: 0
    qDebug() << "1 vs. 3: " << str1.localeAwareCompare(str3); // -1, result: -1
    qDebug() << "3 vs. 4: " << str3.localeAwareCompare(str4); // -1, result: -1
    qDebug() << "3 vs. 5: " << str3.localeAwareCompare(str5); // -1, result: 1 !!!

      I cannot reproduce the problem on other platforms than Android. The problem happens with different locales (I tested English, German).
