При использовании русского, PDF файл генерится в неправильной кодировке. Для исправления ситуации надоиспользовать пакет cmap:

\documentclass[a4paper,11pt]{article}
\usepackage{cmap}
%\usepackage[utf8]{inputenc}
\usepackage[english,russian]{babel}
%\usepackage{graphicx}
%\usepackage{url}
%\usepackage{xcolor}
%\usepackage{ulem}
