This page links to a mixture of different things:
Bash or perl scripts, data about Unicode, data about some non-Unicode
labels (for when trying to find which Small Caps are in a font)
Shell scripts, etc.
I have a number of different templates, several are only working
documents where the formatting of the PDF is not important.
For trying to work out which codepoints are in a file I use get_codepoints,
and for separating a TTC into TTF files I now use my adaptation of getfonts.
These, both individual files and tarballs, are in
Programs to compile (Last tested with gcc-14.1).
There are various XeLaTeX files in lipsum.tex but many are old and might not
compile with recent TeXLive. For monospace and one language where I lack
XeLaTeX source there are old LibreOffice Writer files which I used to create
PDFs, at lipsum.odt.
The XeLaTeX source files for the revised PDF Substitutes files are at
substitutes-tex.
If you have not read H2G2 you might need to read hitchhikers fandom

'go stick your head in a pig'
I am not being insulting, just remembering plans do not always succeed.
