These fonts have terrible coverage. Not even Latin-1 is covered.
You get 80 of the 96 characters in the 0x00a0 to 0x00ff range.
Furthermore, are the fonts actually good for what is claimed?

For ages now, Linux has supported the features required to do
fully private (very secure) /tmp and /var/tmp directories.
It's time to use these features.
First, create a new namespace. As root, do this:

Next, bind-mount something appropria
I'm hearing that files will be provided to activites as hard links.
This is not good. It prevents atomic update via rename.
Far better is to provide directories, one per file, so that
updates can be made atomic. While you can't hard link a directory,
you can bind mount it. This is essentially the

To be clear on why this is rough: it performs an operation
on non-linear data which is only valid on linear data.
That is, it ignores gamma.
