With the text archive there is no problem. The problem occurs only when using the XML archive.

I've checked the xml_iarchive_impl::load impl for std::wstring and there it uses an xml_grammar
to parse out the string, which obviously is why that works. So I would need to do something like that.

Unfortunately there is no way to specialize xml_iarchive_impl::load for my string type, nor is there a way to
call xml_oarchive::save and xml_iarchive_impl::load explicitly (for std::wstring) from load/save implementations (when splitting
serialize into load/save) since they're protected.

For now I split serialize of juce::String into load/save and load/save a std::wstring (with the necessary additional tag)

<myString>
    <std_wstring>StringValue</std_wstring>
</myString>

My end goal is to be able to save my string as:

<myString>StringValue</myString>

Any tips towards that end would be greatly appreciated :)

TIA
