Actually there's really nothing "wrong" with this sign. The dot is legal in email syntax, and in Sweden, the top-level domain is .se, so you could probably assume it's .se and be safe. Websites in other parts of the world don't work like those in the US where it could be .com, .net, .gov, .us, .info, etc. Mostly they just stick with their own national suffix, unless it's an international brand.
