ElementsLocation::pugiXml() and the qet_directory name lookup opened files
with pugixml's load_file(), which on Windows fails once the full path
reaches MAX_PATH. QFile handles long paths, so exist() and the import
succeeded while uuid(), the name, the informations and the thumbnail of
the same symbol came back empty. Read the bytes with QFile and hand them
to load_buffer().
Reported on #1178 as a false collision from qet.addElement.

Another exception: one non-converted code path in projectprintwindow.cpp to be followed-up.
One issue found in the Qt6 code path of diagramview.cpp which has been fixed.
The Qt6 branch of the #if QT_VERSION guard swapped QRegExp for
QRegularExpression but kept calling QRegExp-only methods
(exactMatch()/cap()), which QRegularExpression doesn't have.
Use the correct QRegularExpression API instead: match() returns
a QRegularExpressionMatch, tested with hasMatch() and read with
captured(n).
pugi::xml_document::load_file(const char*) calls fopen/fopen_s on Windows,
which uses the ANSI codepage — not UTF-8. This silently fails when the
collection path contains accented characters (é, ü, ñ, …) or is longer
than the narrow-API MAX_PATH limit, leaving the collection panel with no
element names or illustrations.
Switch both call sites to toStdWString().c_str() which invokes the
load_file(const wchar_t*) overload. On Windows pugixml calls _wfopen,
the wide Unicode API that handles all valid Unicode paths. On Linux/macOS
the same overload converts wchar_t to UTF-8 internally and calls fopen,
so behaviour is unchanged on those platforms.
Affected files:
sources/ElementsCollection/fileelementcollectionitem.cpp (qet_directory load)
sources/ElementsCollection/elementslocation.cpp (element .elmt load, both branches)

The default user-collection path ends in "elements" and the default
company-collection path ends in "elements-company". Both
FileElementCollectionItem::isCustomCollection() and
ElementsLocation::isCustomCollection() used startsWith(customDir),
so "…/elements-company/…" matched "…/elements" and returned true.
This caused ElementsCollectionModel::addLocation() to insert a
newly-saved user-collection element as a child of the company-
collection branch in the tree, making it appear in the wrong panel.
Fix: require the path to equal the directory root exactly, or to
start with the directory root followed by '/'.
path == dir || path.startsWith(dir + QLatin1Char('/'))
