I named a route in greek (?????????) and in my bookmarks it shows up like this: %u0394%u03B1%u03BA%u03C4%u03CD%u03BB%u03B9%u03BF%u03C2
It shows up correctly in the actual route page.
So I'm entering a bug report about it.
I'm also adding that while the greek word that I entered in the forum topic was displayed correctly during preview, it shows up as questionmarks in teh "PENDING APPROVAL" page.
