<p>If I had to guess, I would say that the "dot" fragments are an old way of doing things, and at some point wikipedia (i.e. the mediawiki software) updated to use full-unicode fragments while keeping the "dot" versions for compatibility with existing links. Perhaps there's less cross-browser problems now than back when they came up with the "dot" encoding.</p>
<p>If anyone has anything to back that up, like issues from the mediawiki tracker or links to the source code that would be very useful.</p>
<p>If so, it might be the case that we can just drop the "dot" encoding from the fragments and rely on the non-dot versions that appear to also be available.</p>
