I coudln't find any LoadString in the wineconsole code. Moreover
I accidently found a bug in wineconsole_Fr.rc (French resources)
which contains in the very first line LANGUAGE LANG_ENGLISH, SUBLANG_DEFAULT.
Very likely a cut&paste bug.

Basically all you need is to surround the resources targeted
for different languages by LANGUAGE [main_lang],[sub_lang]
statement. Then just use conventional LoadString, LoadMenu,
etc. functions. They use FindResource internally, which in turn
does search for language dependent resources using algorithm
described in loader/pe_resource.c/PE_FindResourceW.

See dlls/kernel/locale_rc.rc, dlls/kernel/nls/*.nls for string
tables for many different languages but using the same IDs.
They are used by ole/ole2nls.c/GetLocaleInfo.

A much more powerful way to do things would be to use FindResourceEx,
but I would not recommend it, because it adds more power, but requires
more attention since FindResourceEx is not allowed to return any language
resource like FindResource (see PE_FindResourceExW).

Here is an example of using of FindResourceEx to create a dialog
explicitly requesting English resources:

HANDLE hRsrc = FindResourceEx(hInstance, RT_DIALOG, MAKEINTRESOURCE(1), \
                       MAKELANGID(LANG_ENGLISH, SUBLANG_DEFAULT));
VOID *tmplate = LoadResource(hInstance, hRsrc);
DialogBoxIndirectParam(hInstance, tmplate, 0, MyDlgProc, 0);

As I mentioned above, you would better replace FindResourceEx by
simple FindResource here. It will provide a graceful rollback in the
case if resource for a specific language is not exist.

Good luck.
