QString::fromLatin1 always allocates memory, but there are
cases where we can avoid/reduce allocations or/and reduce
text size, e.g.:
QStringBuilder expressions
Fix: replace QString::fromLatin1 with QL1S
QString::fromLatin1().arg(String) pattern
Fix: replace with QStringBuilder
Overloaded functions with QL1S arg
Fix: replace QString::fromLatin1 with QL1S
In rare cases if there is no overloaded function
with QL1S and we have deal with string literal,
replace QString::fromLatin1 with QStringLiteral.

The printf-style version of QDebug expands to a lot less code than the
std::ostream-style version. Of course, you pay in type safety (but
compilers warn about it these days), you cannot stream complex Qt
types and streaming QStrings is awkward, but in many cases you
actually improve on readability.
But the main reason is that something that's not supposed to be
executed under normal operation has no business bloating executable
code size.
This is not an attempt at converting all qWarnings() to printf-style,
only the low-hanging fruit.
In this second part, replace
qWarning() << "" << non-QString
with
qWarning("..%.", non-QString).
QString (and QUrl etc) have special escaping handling when streamed
into QDebug, so leave those alone. They also seem to expand to less
code than the qPrintable() alternative, so there's no reason to
replace them.

The code populated QSets with some strings and went
on to copy the values to QLists. Since QSet is unordered_set, those
lists were not sorted, so the code did that manually.
Since QSet is a node-based container and not even an ordered one,
the code pays a hefty price just for ensuring uniqueness of values
prior to sorting.
The new code just crams everything into lists, duplicates and all,
then sorts the lists and only then removes duplicates using
std::unique.
