I intend to change only the font of a line using LaTeX Font Catalogue, but the whole of document will be changed

Question

While I intend to change the font of only a line in the document using one of the fonts presented in the LaTeX Font Catalogue (https://tug.org/FontCatalogue/mathfonts.html) (for example, concmath: https://tug.org/FontCatalogue/computerconcrete/), but the font of the whole of document will be changed.

I do as follows:

\usepackage{concmath}
\usepackage[T1]{fontenc}
\newenvironment{concmath}{\fontfamily{concmath}\selectfont}{\par}

\begin{document} 
    The font of this text must be remained as it is by default.
    \begin{concmath}
            I want to change only the font of this line using one of the fonts in The LaTeX Font Catalogue.
    \end{concmath}
    The font of this text must be remained as it is by default.
 \end{document}

P.S. I am using LNCS as template and TeXstudio as editor.

How do I use a particular font for a small section of text in my document? — TivV, Feb 10 '20 at 17:40
@TivV Thanks. Do you know where is a complete list, provided there for the Font family and Font name found ? for example, what is the Font family for the font "concmath" ? — Questioner, Feb 10 '20 at 17:40
@Sverre , Yes, meanwhile, Ulrike Fischer's answer works as well. — Questioner, Feb 11 '20 at 13:17

I have extended your MWE so that it is compilable by adding `documentclass{article} as the first line.

% fontprob.tex SE 527806  local font change

\documentclass{article}  % added
\usepackage{concmath}
\usepackage[T1]{fontenc}
\newenvironment{concmath}{\fontfamily{concmath}\selectfont}{\par}

\begin{document} 
    The font of this text must be remained as it is by default.
    \begin{concmath}
            I want to change only the font of this line using one of the fonts in The LaTeX Font Catalogue.
    \end{concmath}
    The font of this text must be remained as it is by default.
 \end{document}

Processing this does typeset with a different font within the concmath environment while not changing fonts outside that.

However there were warning messages such as:

  LaTeX Font Warning: Font shape `T1/concmath/m/n' undefined
  (Font)              using `T1/cmr/m/n' instead on input line 10.

Perhaps your problem is with the LNCS template (whatever that is and however you have used it) and maybe other code you haven't shared. GOM

Thank you. I’m going to test your code tomorrow and share the result here. — Questioner, Feb 10 '20 at 19:47

If you look into concmath.sty you will find a line \renewcommand{\rmdefault}{ccr}. This gives you a clue about the family name of the font.

\documentclass{article}  % 
\usepackage[T1]{fontenc}
\newenvironment{concmath}{\fontfamily{ccr}\selectfont}{\par}

\begin{document}
    The font of this text must be remained as it is by default.
    \begin{concmath}
            I want to change only the font of this line using one of the fonts in The LaTeX Font Catalogue.
    \end{concmath}
    The font of this text must be remained as it is by default.
 \end{document}

It works. But, now another problem: after \end{concmath}, a new paragrapg is generated. How to continue in the same line after \end{concmath} ? Thanks – Questioner Feb 11 '20 at 10:50
Don't use a \par in the environment if you don't want it (it was from your example). – Ulrike Fischer Feb 11 '20 at 10:52
Yes, I removed \par and it is now like this: \newenvironment{concmath}{\fontfamily{ccr}\selectfont} , but yet a new paragraph is created after \end{concmath} , strange! – Questioner Feb 11 '20 at 10:59

there is no paragraph, but you should probably use {\ignorespaces} as the second argument. – Ulrike Fischer Feb 11 '20 at 11:01
Yes, it works. Thanks – Questioner Feb 11 '20 at 11:03
