The microtype package

CONFIGURATION FILES: Additional kerning 18915.10.1 FrenchThe ratio of \fontdimen 2 to \fontdimen 6 varies for different fonts, so that eitherthe kerning of the colon (which should be a space, i.e., \fontdimen 2) or that ofthe other punctuation characters (TEX’s \thinspace, i.e., one sixth of \fontdimen 6)may be inaccurate, depending on which unit we choose (space or 1em). For Times,for example, a thin space would be 665. I don’t know whether French typographyreally wants a thin space, or rather (as it happens to turn out with CMR) half aspace. (Wikipedia 26 claims it should be a quarter of an em, which seems too muchto me; then again, it also says that this was a thin space in French typography.)7568 \SetExtraKerning7569 [ name = french-default,7570 context = french,7571 unit = space ]7572 { encoding = {OT1,T1,LY1} }7573 {7574 : = {1000,}, % = \fontdimen27575 ; = {500, }, % ~ \thinspace7576 ! = {500, },7577 ? = {500, }7578 }7579These settings have the disadvantage that a word following a left guillemet willnot be hyphenated.
