¶Thanks, but only my computer speaks Japanese
Due to some recent testing, I currently have the system locale on my Windows 7 x64 system set to Japanese, but with location and language settings still set to US English. I haven't changed it back because I'm too lazy to reboot.
Imagine my surprise when I tried to get help from the Open Watcom disassembler:
Needless to say, this is less than helpful considering the only Japanese words I can read are those for OK, cancel, yes, no, item, attack, save, and idiot.
I'm pretty sure that you are not supposed to use the ANSI code page (GetACP) or otherwise system locale setting for language selection. Sadly, a quick search over MSDN reveals that Microsoft's guidance is less than clear.
