Keyboard shortcuts don't work if non-English layout is used

The IntelliJ shortcuts don't work (e.g. commenting a line: Ctrl + /) if I set my keyboard layout to Spanish. If I switch the layout to English, then the shortcuts work as expected. Is this a bug or can be fixed somehow in the IDE? I don't want to manually change all shortcut mappings. I'm also using Eclipse and this problem doesn't happen so it seems an IntelliJ-only thing.
