Hi Zdenék,

I'm only a hacker and tester, not a typographer.  I usually take the
"is it good enough?" approach, often for low values of 'good
enough'.

What I'm trying to do is document available OTF and TrueType fonts
for my (non-https) site at http://zarniwhoop.uk/.  My aim is to
indicate which languages a font covers, and to show examples of how
it looks, so that people can make choices about which fonts might
work for them.  From time to time I take a deep dive into wikipedia,
and I hate seeing 'tofu'.

There are a number of fonts I've seen mentioned recently which might
be interesting, and a few other fixups to presentation (e.g.
changing some of the so-called lipsum files I've uploaded).  All
that I generally show is Article 1 of the UDHR (if the online
versions I've found are correct).

As an example, I've temporarily uploaded a pdf of my new template,
containing all the possible languages I might want to show.

https://www.linuxfromscratch.org/~ken/tmp/languages-full.pdf

Compared to previous versions it now correctly picks up bold and
italic fonts, some rewording, and corrected the pilcrow which had
accidentally beeen a reversed pilcrow.  The template shows
FreeSerif which does include some of the languages you care about,
as well as a lot of tofu for other things.
