I want to compile the LX fonts demo on LuaLaTeX. Because I would want to use this font for my future presentations. Furthermore, I only use LuaLaTeX.

I'm not sure how to correctly proceed to rearrange the code to be compatible with LuaLaTeX and not pdfLaTeX. In addiction, I'm not sure if this is possible because:

Personally I believe that T1 encoded fonts should be the only ones to be used, unless the user has access to suitable UNICODE encoded OpenType fonts, but this is out of topic since these LX fonts can be used only by pdfLaTeX, that cannot directly handle OpenType fonts.

I know that fontenc and inputenc are not necessary on LuaLaTeX then I commented out their lines in the preamble. Then I compiled the code

latexmk -interaction=nonstopmode -synctex=1 -lualatex ./LXfonts-demo.tex

Unfortunately, it failed with

Missing character: There is no μ (U+03BC) in font [lmroman10-regular]:+tlig;!Missing character: There is no ₲ (U+20B2) in font [lmroman10-regular]:+tlig;!] [16

If you remove inputenc (keeping fontenc) you get:

The above is all you need for Latin but you also need to force legacy encoding for Greek. I think this is enough, but I can't read greek...

Declare LGR and T1, so change the fontenc line to

\usepackage[LGR,T1]{fontenc}

Force Greek to use the legacy LGR encoding

\begin{otherlanguage}{greek}\fontencoding{LGR}\selectfont

  • Thank David! I commented out inputenc and the compilation is successfully finished. Unfortunately I noticed that the Greek quote slide is composed with Latin chars. Did it happen to you? – miticollo Oct 03 '23 at 17:57
  • @miticollo try now.... – David Carlisle Oct 03 '23 at 18:11
  • Thank again! I notice another problem. If you compile with latexmk -interaction=nonstopmode -synctex=1 -pdflatex ./LXfonts-demo.tex the output is different from the PDF on CTAN (on the left side a slide from lxfonts.pdf on CTAN, on the right the same slide has just compiled). I don't understand if this is an expected behavior or not: after all lxfonts.pdf was compiled ten years ago. – miticollo Oct 03 '23 at 23:10
  • different monospace, what compare the output of pdffonts on the two pdf? @miticollo – David Carlisle Oct 03 '23 at 23:13
  • See the diff. It is done on previous slide (12) and as before on the left the original PDF from 2013 while on the right mine. – miticollo Oct 03 '23 at 23:58
  • David, I found a solution (maybe). It seems that SFLTT8 is a font family in cm-super. But if you use \usepackage[T1]{fontenc} you can't use the CM-fonts.

    Now, is it possible to use this font family on LuaLaTeX? See it is going to be tough.

    If you really want the original 7bit cm fonts then use OT1 rather than T1 but by then it's not clear why you would use luatex at all as you are disabling all its font features (but do have lua of course) @miticollo But I think you misunderstood my referenced answer you can use cm-super with T1 encoding, you just can not use the original Knuth fonts (which are 7bit OT1 not 8bit T1) – David Carlisle Oct 04 '23 at 12:03
  • I solved the problem on slide 12 adding to preamble \DeclareTextFontCommand{\texttt}{\usefont{OT1}{llcmtt}{m}{n}} or changing \usepackage[OT1]{fontenc}. Doing this \texttt uses CMTT as font. Anyway there is another problem on slide 6 and I don't know how to solve it.

    Finally I tried the original demo on Overleaf (with TeXLive2014 + pdfLaTeX) and the same problems happen.
