I pushed the rebased old commits and, immediately afterwards, the new commits, but apparently that was too quick for gitlab since it's ordering the two pushes the other way around :rolling_eyes: I added a couple more patches at the end that cover computing and storing the KLID and the layout id respectively. The "unknown" id computation is maybe a bit more complicated than it needs to be, it does give nice numbers though :sweat_smile: The `0x20` used in the KLID computation was chosen to stay clear of the highest ids currently in use (which is Osage on the LOCALE_CUSTOM_USER_DEFAULT 0xc00 LANGID, https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/windo...) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10779#note_139990
