Because T E X needs a couple of so called fontdimens to be set, the comments list the appropriate values. When a tfm file is generated from an afm file, these values have to be used. Each character (or glyph) gets an entry. When we run out of indices i.e. pass the 255 boundary (we start at 0) the index becomes -1. Only the width is specified. The height and depth have to be derived from the bounding box for which the specification starts with key B. StartCharMetrics 821 ... C 32 ; WX 333.33333 ; N space ; B 0 0 0 0 ; ...

EndCharMetrics Watch how this font defines a space character and keep in mind that these fonts date from the time that there was only one kind of space. The L entry specifies a ligature. The names of glyphs are standardized, and even the f_k is conforming to standards. This standardization makes it possible to go back from glyphs to characters when copying text from a typeset document. The kern table is pretty large here and for a reason. First of all the file defines 821 glyphs so the average amount of kerns per glyph is not that large. But take a look at the A. Because the Aacute has the same shape it kerns in a similar way. This means that ideally all combined characters end up with the same value as their base glyph. However, in our case a bit more selective approach is taken. The Adieresis has a different set of kerns, probably to save space. It is for this reason that OpenType fonts have a model of kern classes so that similar shapes can be treated as one when setting kerns. You see a similar issue with ligatures, where often the right part of the shape kerns the same as the (stand alone) first part of the shape does. StartKernData StartKernPairs 9230 153 Appendix
