To escape underscore without \verb and \texttt

Question

I know this thread which implementation is about verb and \texttt such that you have something inside the phrase. I do not want to change the phrase at all. I want to have this as text in my document

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
hp_feb04_macro.pdf
\end{document}

Unsuccessful attempts for hp_feb04_macro.pdf

\verb|hp_feb04_macro.pdf|

which changes the uncerscore something something else (-, I think). And

\texttt{hp\_feb04\_macro.pdf}

which I do not like since my desktop search is then deteriorated.

How can you have underscore in your text without \verb and \texttt?

With \usepackage[T1]{fontenc}, when you copy the underscore produced by \_, you get an underscore. — egreg, Mar 09 '15 at 13:30
@egreg Yes, I know. But I do not want change the name "hp_feb04_macro.pdf" by any method. Putting "" changes the name and deteriorates my search. — Léo Léopold Hertz 준영, Mar 09 '15 at 13:35
This is a different question! I do not want verb and nothing inside the escaped phrase. — Léo Léopold Hertz 준영, Mar 09 '15 at 13:43
Actually, not duplicate of the second proposed topic by Joseph, since I do not want to change the content of the text. Good idea is provided below. — Léo Léopold Hertz 준영, Mar 09 '15 at 16:12

If you need to use your hp_feb04_macro.pdf in some macro, enclose the macro inside the \startunderscoreletter and \stopunderscoreletter pair.

\documentclass{article}
\usepackage[T1]{fontenc}
\newcommand{\startunderscoreletter}{\catcode`_ 12\relax}
\newcommand{\stopunderscoreletter}{\catcode`_ 8\relax}
\begin{document}\thispagestyle{empty}
\startunderscoreletter
hp_feb04_macro.pdf
\stopunderscoreletter

test math $a_i$
\end{document}

underscore
