it in several places. Currently these places get a Sequence<sal_Int8> by call of StaticTokenMap().getUtf8TokenName() and immediately after that generate an OUString from it using reinterpret_cast<const char*> and the OUString ctor with 8-Bit character buffer array. The patch moves this conversion to StaticTokenMap.
