Unicode has lots of characters that look alike, because, well, lots of human languages ended up with similar-looking characters.

Even English speakers will easily confuse 1,I, and l, depending on how they're represented by the browser. And 0/O.

For more fun, try drawing any shape on http://shapecatcher.com/ and see all the similar-looking Unicode characters.
