The typographers at Hoefler & Frere-Jones share some of their Adventures in Kerning:
A kerning table, which makes special allowances for characters that don’t fit together naturally, can reveal a lot about the personality of its designer. Every font pays special attention to the pair Va, but the font that includes Vr suggests a familiarity with French (vraie) or Dutch (vrou). Pairs like Wn or Tx hint at an even broader perspective (Wnetrzne, Poland; Txipepovava, Angola), and the designer who kerns the ¥4 has presumably spent some time thinking about finance. Including ÅÇ is the mark of someone who’s trying too hard: these letters don’t nest together naturally, but nor do they appear together in any language.When I first learned about kerning, mystifying to me was the presence of Yq in almost every one of Adobe’s fonts. Adobe’s early faces sometimes neglected far more common pairs, or even whole ranges of the character set — many fonts didn’t kern periods, dashes, or quotation marks — but Yq was ever-present. When I met him in the early nineties, Adobe’s Fred Brady hinted at why: located in northern California, Adobe’s designers often had a thing for viniculture, and one of the world’s most famous dessert wines is produced by Château D’Yquem.
