I don't see how you arrive at that. If I assume perhaps twenty or so ranges of 256 chars. for a very large font family (including greek letters, punctuation and more -- and I assume that this would cover CM, Knuth's font and the one I am using) I come up with roughly 5K characters. And it seems to me that the kerning pairs would be 5K to the power of 2 (not 2 to the power of 5K) -- though I admit that as a non-mathematician I only arrived at this by putting five letters on a page and adding up the possible pairs (AA, AB, AC, AD, AE, BA, BB, etc.); this gave me 25, not 32. Anyway, one can assume (I would have thought) that Knuth would have worked in an optimal manner and therefore paid particular attention to the most common possible combinations (such as the basic lower- and uppercase letters and punctuation). I can only assume that there was a good reason that such pairs as "-W" kern as they do... -Kevin -- Kevin Pfeiffer <[EMAIL PROTECTED]> Tiros-Translations
