Interesting how your first link get displayed in fixed-width Asian-style characters here in Chromium, apparently because of the apostrophe (which itself is the only character displayed with a narrower width). Just removing the apostrophe in Chromium's address bar immediately makes all the text go back to a normal font. Firefox just shows "%C2%92".
Actually, it looks like what gets displayed as an apostrophe is just a control character, U+0092 <control> = PRIVATE USE TWO.
