I am not attempting to dissuade anyone from using paps but trying to
explore why what appears to be a relatively simple process (text to PDF)
has so few utilities. Without a UTF-8 requirement we are awash with
Postscript programs, but not so with direct conversion to PDF. Having
said that, I have no deep understanding of either the PostScript or PDF
format, so perhaps it is more difficult than I imagine; especially when
it comes to producing an output with, for example, columns, headers etc.
However, there are utilities which can help with preprocessing a text
As a UTF-8 Debian alternative to txt2pdf:
Create $HOME/.config/fontconfig/fonts.conf with the contents
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
(Is there anything better than FreeMono's UTF-8 glyph coverage?)
CHARSET=utf-8 /usr/lib/cups/filter/texttopdf 1 1 1 1 1 < text.txt> > out.pdf
out.pdf is not searchable, so continue with
pdftocairo -pdf out.pdf searchable.pdf
A bonus is that searchable.pdf is about seven times smaller than out.pdf.
