The utility muirct.exe for some reason accesses the opaque HANDLE that is returned by BeginUpdateResource, it assumes a certain structure in which (on 32bit systems) there is a pointer to the wide repesentation of the file name in offset 0x18 (0x30 on 64bit).
Refer to: muirct!BldToolsEndUpdateResourceW called from muirct!CopyChecksumToFile
Sample execution: MUIRCT.EXE -c "ui.exe" -e "de-DE\ui.exe.mui"

You only need first two fields, the rest is wine-specific. Also comment is redundant imho, and 'Reserved' means 'Unknown' here.
