o Add File to the mUefiDevicePathLibDevPathFromTextTable table so we don't include 'File()' in the supposed path name. This happens because of a possible misfeature in the EDK2 code where any path that's not recognized is treated as a File() node. o Convert utf8 input into ucs2 output rather than just copying the utf8 and hoping for the best (no good comes from that). o Remove bogus comment about needing to add 1. The dummy array already is length 1, so that's included in sizeof the struct, so there's no need to add it. Sponsored by: Netflix
