rmligs – Remove incorrect ligatures in German documents

Li­ga­tures, which are a pleas­ing fea­ture of TeX's use of fonts, should not be placed in Ger­man words be­tween the word stem and the rest of the word.
The rm­ligs pack­age is a perl script that takes in­put in ISO 8859-1 or -15, UTF-8 or LaTeX-style um­laut en­cod­ings ("a, "u, etc.), and in­serts a break where an in­ap­pro­pri­ate lig­a­ture would ap­pear. So, for ex­am­ple, ‘Au­flage’ will be changed to ‘Auf"|lage’, which type­sets in a ty­po­graph­i­cally cor­rect fash­ion.
