Neovim nowadays always use UTF8 for RPC (:h encoding). This change reduces the dependency on neovim-qt for that particular thing and uses Qt built-in mechanism instead.
neovim-qt now uses internally QTextCodec internally to decode/encode strings, but in Qt6 it was removed, so they planned[^1] to ditch it and force UTF8 anyway, because of the same reason.
While they are at it, we can use the internal Qt functions instead.
