Please hope me! Far from home and locked out of my Mac due to international language keyboard issue. Thanks for reading ... and here's a puzzle for you advanced Mac-heads out there:

I'm visiting Istanbul and learning Turkish, so I've had my (recent model) MacBook Air's keyboard set to "Turkish-QWERTY", and my account login password was a Turkish word ("ho?geldiniz"). All of which worked great until the other day when, before writing an email in English, I switched the keyboard setting back to "standard US".

Oh no! Ever since, every time I try to log in to my Mac I get rejected. That's because the US keyboard can not, in any way, make the ? in my password. And the big catch-22 is that it seems to be impossible to switch back to the Turkish keyboard without first logging in!

I can't believe that something so simple would brick my computer. Worst of all, I don't have any kind of system recovery chip, and I'm in Istanbul where there's no Genius Bar. And finally, just to round things out, I have the flu and am running a 102º fever. Help ...?
