The Kerning Table
The kerning table, with a tag name of'kern', is an optional table that contains the values you can use to adjust the spacing between glyphs in a font. Kerning can be parallel to the flow of text or perpendicular to the flow of text. For example, if you specify perpendicular kerning and if text is normally read horizontally, the glyphs are kerned vertically. Kerning is always applied to pairs of glyphs.The kerning table in the outline font resource consists of a header and a series
of subtables. The TrueType Font Format Specification documents a basic set of kerning subtables.
