MSVC420 doesn't support UTF-8, so the (R) symbol must be in Windows-1252 encoding instead. A PR seems to have reverted this back to UTF-8 (a code editor probably did this without even mentioning it)
In 1.0 WINDOW_TITLE seems to be a define like WNDCLASS_NAME. However, in
1.1 it is a const char* like in the already existing code. It also has a
value of "Lego Island" in 1.0 but a value of "Lego®" in 1.1.
