There doesn't seem to be an override for the + operator for QLatin1String, so it has to convert to UTF-16 anways. There are a bunch of such cases below as well.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I double checked against QStringBuilder, and I don't see it helping either. It still does the conversion anyways.</p></pre>

Using QStringLiteral there would not gain you much.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If there is not +operator for QLatin1String then it should be added upstream.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Anyhow, imo this can be pushed as-is and anything else improved later on if need be.</p></pre>
