Cannot copy letters with diacritics from pdflatex PDF

Question

I have problem with copying text from PDF file.

I am using these packages in my document:

\usepackage[slovak]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

However when I generate PDF file, it doesn't allow me to copy slovak characters. For example copying this

nemožné k nim pristupovať

results in

nemoºné k nim pristupova´

Do you have any idea how to solve it?

Answer 1

Adding package lmodern solved my problem:

\usepackage{lmodern}

Answer 2

With reference to page 7 in the MinioPro-manual, to make figures and ligatures searchable, you need to enable glyphtounicode translation and load the default mapping table:

\input{glyphtounicode}
\pdfgentounicode=1

glyphtounicode was included in my MikTeX-distribution, but if it is not included in yours, you can find it at Sarovar.
