Can not type the @ symbol

I type the @ symbol using ALT GR + V on my slovenian keyboard. But since 1.8-pre1 this combination is recognized as CTRL + V while I type in chat, command blocks and books.

I can not type the @ symbol, I have to copy and paste it. This only occurs in Minecraft, the key combination is properly recognized elsewhere [Web pages, Microsoft products, in other games etc.].

The issue is probably not Minecraft related and happened due to other changes in my system. But it is definitely suspicious, so I decided to report it here.

EDIT: ALT GR + V works properly when I am writing a sign.

EDIT 2: In the time since I posted this, I have tried it on several other computers with a Slovenian keyboard and it did not work. It must be an issue with updating Minecraft to 1.8 and not with my other system settings.
