I had a similar experience. I'm based in the UK so I have my computer set up to use a UK keyboard layout. One time, I decided to use the # symbol in my Windows password. The next time I tried to log in to Windows, my password was rejected. I eventually discovered that Windows was using a US keyboard layout until I logged in, meaning that # was in a completely different location on the keyboard and I was typing a completely different character. Of course, there's no option to actually see your password while you type it so it took me a long time to realise that I had to type shift-3 to get that character. I'm used to getting £ when I hit shift-3, that being the pound sign that we user over here.
