The rationale is explained in https://planet.kde.org/friedrich-kossebau-2023-06-28-include-also-moc-files-of-headers/
In case of KDEConnect, it impressively speeds up compilation. Before it
took 390 seconds on a clean build and with this change it took 330 seconds.
This is due to the mocs_compilation having to include the header files
and thus all their headers. Due to the lots of small plugins we have,
this means that the same headers must be compiled plenty of times.
When we include the moc files directly in the C++ file, they are already
available.
Unicode text input from remote devices gives random texts because the plugin mistook the text encoding. Insert a Unicode 16 bits character each time instead of a UTF-8 character.
The API accepts the `UniChar` Unicode characters:
```c
void CGEventKeyboardSetUnicodeString(CGEventRef event, UniCharCount stringLength, const UniChar *unicodeString);
```
