# Ligatures disabling

I want to disable ligatures when I am typing letters, however, I need '--' to be joined to a long dash. Is it possible to make this?

Now I am avoiding it like this

\usepackage{microtype}
\DisableLigatures{encoding = *, family = * }

Use \textendash for the en-dash. –  egreg May 29 '12 at 8:52
Why is it better than just type double dash? –  Pavasaris May 29 '12 at 9:48
If you disable all ligatures, that command will use the en dash anyway. –  egreg May 29 '12 at 9:50

You can only do it the other way round as described in the documentation of microtype. You can give a list of chars for which ligatures should be disabled:
\documentclass{article}
