A font never retreats. > More seriously, Iʼm assuming this is the maximum width of a character > in the font, in which case we should say so. No, it's the maximum, over all the characters of the font, of the number if pixels to advance after drawing a character. It could be different from the character width when there are overlaps. I'm not sure we should go into such details here, because describing the fundamentals of digital typography is well out of scope of this manual. People should look elsewhere for the detailed information about this.
