symbolsunicode
I'm new to LaTeX and I don't know how to use the CTAN package for typing APL symbols. So far I use the wasysym package but symbols like the ⍎ (down tack jot) are not included.
I have downloaded the apl CTAN package which is a directory of various files but I can't find instructions on how to use it in my LaTeX editor (TeXworks).
Please can you tell me how to use this package?
You need at first a tfm-files with the metrics. (If you have an afm-file it is easy to generate the tfm with afm2tfm.) Put at first the tfm and the pfb in the same folder as your test document to test the font. In a small latex document add the line
\pdfmapline{=tfm-name fontname type1.pfb} (with the correct names) and then try the positions where your symbols should be. Here an example how such a test looks like with the wasy font:
\documentclass{article}
\pdfmapline{=wasy10 wasy10 <wasy10.pfb}
\begin{document}
\font\test=wasy10 \test \char62 \char63
\end{document}
When this works make a list of all symbols, their positions, the command names you would want to use, the name of the tfm and the pfb, so that someone can make a you a small sty and a map-file.
Edit:
Next step: The map file. As you could see pdflatex can load the mapping information simply with \pdfmapline (or \pdfmapfile), but dvips, dvidpfmx etc need the informations in their maps.
Make a wpl.map which contains the line from the \pdfmapline (without the equal sign). Save it in a local texmf tree in somewhere below /fonts/map/.... While you are at it move also the other files to the local texmf tree. Update the FNDB/run texhash. Then add the map file with updmap-sys (normally) or updmap (miktex and in special cases with texlive). See also the TeX-FAQ: http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instt1font.
Then test again. At first with pdflatex. When it works try with dvips. If it works with pdflatex but not with dvips then the "font name" (the middle entry) in the map line is wrong (dvips is more picky). Check the correct name in the afm, correct in the map and regenerate the maps with udpmap(-sys)
You can load the relevant font encoding, namely T5.
\begin{filecontents*}{\jobname.bib}
@article{test,
author={\viet{Hồ Thiện}},
title={Title},
journal={Journal},
year=2020,
}
\end{filecontents*}
\documentclass{article}
\usepackage[T5,T1]{fontenc}
\newcommand{\viet}[1]{{\fontencoding{T5}\selectfont#1}}
\begin{document}
\cite{test}
\bibliographystyle{plain}
\bibliography{\jobname}
\end{document}
If needed for sorting, you might include a dummy argument, say
\newcommand{\viet}[2]{{\fontencoding{T5}\selectfont#2}}
and change the entry in the .bib file to
\viet{HoThien}{Hồ Thiện}
