[PATCH 0/2] MR10122: kernelbase/loader.c: Include rudimentary support for multilanguage resource inclusion.
For programs that rely on language specific data for resources such as menus and text, attempt to search for and associated "mui" file. For example, if program "myapp.exe" is executed and resources are not found, and the user's language ID is "ENU", search for file "myapp.ENU", and if found, utilize that file for the source of resource data. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10122
