Unicode character ✔ (U+2714) not set up for use with LaTeX error while building with pdfTeX

pdftexunicodeutf8

For the test case:

\documentclass{article}
\usepackage{ifxetex}
\ifxetex
    \usepackage{polyglossia}
    \setdefaultlanguage{english}
    \defaultfontfeatures{Ligatures={TeX}}
    \setmainfont[BoldFont=cmunbx.otf, ItalicFont=cmunti.otf, BoldItalicFont=cmunbi.otf]{cmunrm.otf}
    \setsansfont{CMU Sans Serif}
    \setmonofont{CMU Typewriter Text}
\else
    \usepackage[T1]{fontenc}
    \usepackage{textcomp}
    \usepackage[utf8]{inputenc}
\fi

\begin{document}
\section{Main}
Euro (€): ^^e2^^82^^ac\par
Heavy Check Mark (U+2714): ^^e2^^9c^^94\par
% ✔
\end{document}

got error:

Unicode character ✔ (U+2714) not set up for use with LaTeX. Heavy Check Mark (U+2714): ^^e2^^9c^^94

while building with PDFLaTeX.

There are lot of similar issues here, but even solution from the closest one (Unicode characters in pdflatex output using hexcode without UTF-8 input) didn't work. How to fix it?

No such error while building with XeLaTeX (though it draws characters incorrectly, so suggestions how to fix it are also appreciated).

Best Answer

Hoping to have a file that compiles with both XeLaTeX and pdflatex is, I'm afraid, generally hopeless.

In any case, XeLaTeX doesn't accept input such as ^^e2^^82^^ac; actually it does, but the result is not what you seem to expect.

You can set up replacements for missing symbols. I also redefine the Euro symbol for pdflatex, because the one you get with European Modern is “funny”.

\documentclass{article}

% general packages
\usepackage{iftex}
\usepackage{newunicodechar}

% specific packages
\iftutex
  % XeLaTeX or LuaLaTeX
  \usepackage{polyglossia}
\else
  % pdflatex
  \usepackage[T1]{fontenc}
  \usepackage{pifont,eurosym}
\fi

% settings

\iftutex
  % XeLaTeX or LuaLaTeX
  \setdefaultlanguage{english}
  %\defaultfontfeatures{Ligatures={TeX}}
  \setmainfont{cmun}[
    Extension=.otf,
    UprightFont=*rm,
    BoldFont=*bx,
    ItalicFont=*ti,
    BoldItalicFont=*bi
  ]
  \setsansfont{CMU Sans Serif}
  \setmonofont{CMU Typewriter Text}
  \newfontface{\extrasymbols}{FreeSerif}[Extension=.otf]
  \newunicodechar{✔}{{\extrasymbols ✔}}
\else
    %\usepackage{textcomp}
    %\usepackage[utf8]{inputenc}
    \newunicodechar{✔}{\ding{52}}
    \newunicodechar{€}{\euro}
\fi

\begin{document}

Euro (U+20AC): €

Heavy Check Mark (U+2714): ✔

\end{document}

Output with XeLaTeX

Output with `pdflatex`

[Tex/LaTex] Error: Unicode char \u8:φ not set up for use with LaTeX

The inputenc package, even with the utf8 option doesn't load all the Unicode tables. It loads only those for which it knows it will have to typeset some glyphs.

You have then to teach the proper environment, because each Unicode block requires a different TeX fonts (they have only 256 characters).

So your example works with pdflatex, but modified into the following code.

\documentclass{article}
\usepackage[LGRx,T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{CJKutf8}
\begin{document}

\foreignlanguage{greek}{φΔδ}\begin{CJK}{UTF8}{gbsn}汉\end{CJK}

\end{document}

This is admittedly largely impractical for extensive usage of characters belonging to different blocks, so it may be advisable to switch to XeLaTeX or LuaLaTeX that can use OpenType fonts.

enter image description here

Important update

After release of Babel version 3.9, the LGRx encoding should not be used any more. Now LaTeX is able to interpret correctly UTF-8 characters for Greek out of the box, provided the Greek language is loaded with babel. So the example above becomes

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{CJKutf8}
\begin{document}

\foreignlanguage{greek}{φΔδ}\begin{CJK}{UTF8}{gbsn}汉\end{CJK}

\end{document}

[Tex/LaTex] ! Package inputenc Error: Unicode character ⁡ (U+2061) (inputenc) not set up for use with LaTeX

U+2061 is FUNCTION APPLICATION that is an invisible zero width character intended to distinguish concatenation meaning function application from concatenation meaning multiplication,. You should be able to simply delete it.

If deleting it is hard then declare it to do nothing add this to the document preamble
