The use of long s versus short s and ligaturing of these letters varies widely geographically and historically and depending upon typeface. The following examples would all be valid *if* s-VS1 were to be defined as a variation sequence for long s (in all type styles): s-VS1-ZWJ-s-VS1-ZWJ-i -- for a ligatured ſſi as in "miſſion" (usual in 18th century English typography) s-VS1-s-i -- for a non-ligatured ſsi as in "illuſtriſsimos" (usual in 18th century Spanish typography) s-VS1-ZWJ-s-i -- for a ligatured ſs plus i as in "bleſsings" (usual for italics only in 16th and early 17th century English and French typography) s-s-VS1-ZWJ-i -- for s plus a ligatured ſi as in "utilisſima" (sometimes in 16th century Italian typography) Andrew
