\documentclass{article}
\usepackage[T1,OT4]{fontenc}
\begin{document}
Text with \_.
\end{document}
In PDF there is a correct output: Text with _.
But when I select and copy it I get: Text with .
It happens on Adobe Reader, Foxit Reader and on Sumatra PDF so I think it is not a reader issue.
How can it be fixed?
Change to
\usepackage[OT4,T1]{fontenc}
As far as I can see it, you don't really need the OT4 encoding; according to this remark from the fontenc documentation referring to OT4:
While Knuth included the means of typesetting the ‘lost L’ (Ł) in his OT1 encoding, he omitted the ogonek, a diacritic mark that is also needed in Polish text; hence the appearance, well before the
T1encoding, of fonts using this encoding.
So you can simply say
\usepackage[T1]{fontenc}
\usepackage[T1,OT4]{fontenc} in my real document. I think I need OT4.
\usepackage[OT4,T1]{fontenc}; by the way, you should have mentioned this in the question.

\usepackage[T1,OT4]{fontenc}.
"Old" fontencodings like OT1 or OT4 don't have a glyph for \_ (\textunderscore), they use the default defined in the kernel which is a small rule. But you can change this default so that the glyph from the T1-encoding is used instead:
\documentclass{article}
\usepackage[T1,OT4]{fontenc}
\DeclareTextSymbolDefault{\textunderscore}{T1}
\begin{document}
Text with \_.
\end{document}
OT4andT1)?
