• Perhaps you should show us the compilable code that produces this, but I guess it's something with font or input encoding – user31729 May 13 '16 at 15:32
• Please give us a full compilable minimal working example so we can test it. And let us know what command you're using to compile (pdflatex, xelatex etc.). It's a font issue as "fi" is a ligature - a single character which is missing in your font. Finding out why is the important part – Chris H May 13 '16 at 15:33
• The problem is your source code is using unicode fi ligature, but you have not enabled it in the output. delete the fi character and replace it with f and i. – Steven B. Segletes May 13 '16 at 15:38

You are inputing the fi as the unicode character U+FB01. Either replace this by "fi" or use inputenc and define a suitable replacement:

\documentclass[12pt,a4paper,oneside]{article}
\usepackage[utf8]{inputenc}
\DeclareUnicodeCharacter{FB01}{fi}
\begin{document} \thispagestyle{empty}

\section{Introduction} connectivity, which can be either X-DSL or ﬁber.
