Completely off-topic, your post demonstrates the profound stupidity of Unicode ligatures. Ligatures are a typographic trick to make certain sequences of letters like "fi" and "ffi" look pretty when displayed in some media. Comically, the Unicode ligatures not only make life a royal pain for regular expression matching, but they're also ugly as sin (compare the actual "fi" to the "fi"-ligature here). They're even less useful than pages of emoji.
