No U+2003 in Latin Modern Roman 12 Regular

latin-modernunicode

I am using the OTF variant of the Latin Modern Fonts on my system (Linux Ubuntu) with XeLaTex. http://www.gust.org.pl/projects/e-foundry/latin-modern

I cannot set an Em Space : https://www.compart.com/de/unicode/U+2003
since there is a warning

[WARNING] Missing character: There is no   (U+2003) (U+2003) in font Latin Modern Roman 12 Regular

Why is this? I thought the font was Unicode capable?

MWE:

\documentclass[
  12pt,
  paper=a4,
  twoside,
  titlepage=true,
  openright,
  abstract=on,
  toc=listofnumbered,
  numbers=noenddot,
  chapterprefix=true,
  headings=optiontohead,
  svgnames,
  dvipsnames]{scrreprt}
\usepackage{amsmath,amssymb}

  \usepackage{unicode-math}
  \defaultfontfeatures{Scale=MatchLowercase}
  \defaultfontfeatures[\rmfamily]{Ligatures=TeX,Scale=1}
  \setmainfont[]{Latin Modern Roman}
  \setsansfont[]{Latin Modern Sans}
  \setmonofont[]{Latin Modern Mono}
  \setmathfont[]{Latin Modern Math}


\begin{document}
EN space     
\end{document}

Just because a font is “Unicode capable” doesn't mean it has to support every single glyph. The easiest LaTeX way in my opinion would be to simply use \quad.

That said, if you regularly have these kind of spaces in your document and want to deal with them automatically, check out the uspace (as in “Unicode Space”) package. https://ctan.org/pkg/uspace

It also supports zero width space (U+200B), three-per-em space (U+2004), four-per-em space, thin space (U+2009), hair space (U+200A) and others and works with all fonts.
