encxvlna – Insert non­break­able spaces, us­ing encTeX

The pack­age pro­vides tools for in­sert­ing non­break­able spaces af­ter non­syl­labic prepo­si­tions and sin­gle let­ter con­junc­tions as re­quired by Czech and Slo­vak ty­po­graph­i­cal rules.
It is im­ple­mented us­ing encTeX and pro­vides files both for plain TeX and LaTeX. The LaTeX so­lu­tion tries to avoid con­flicts with other pack­ages.
