These are a selection of PDFs containing dummy text, to provide examples of how
various fonts compare. Many of these files are old.

Originally I used random lorem ipsum text for Latin Sans and Serif, and text
from catipsum.com for the monospace (because monospace is particularly used for
coding, and managing coders is like herding cats). All the files except for the
monospace versions were created in xelatex. For monospace, I used libreoffice
writer to avoid xelatex adding microspacing - at one point I thought I had found
a fix for xelatex, but in 7-line paragraphs only the first 5 lines had all the
character columns aligned.

N.B. - using many fonts in a lowriter document seemed to provoke it to lock up
at 100% of 1 CPU - frequent saving, and killing soffice.bin became necessary. Of
course, using many fonts in one document is a very unusual use-case and I have
no idea of the current status of doing that.

There have been various changes over the years, the current position is that the
Latin Serif fonts (Old-style, Transitional, Modern) should be OK and I think I
tried to use a similar amount of text for each font. I also added comemnts about
font wieghts and the coverage of italics/sland and small caps (if I can identify
the available small caps). Finally, I added comments about Cyrillic or Greek
coverage using Polyglossia (non-Latin fonts need specific OpenType tags) - the
comments might be slightly wrong now - I had not realised that my builds of
TeXlive could have accents and variants of hyphens or dashes generated by
Harfbuzz.

For many of the older files for other languages, I tried using Google Translate
on random text (catipsum, maybe other sources) and probably ended up with total
gibberish (but then Lorem Ipsum is degraded and jumbled Latin). I think I took
a translation of Lorem Ipsum and got the follwoing, maybe I used that for some
of hte translations:

Those who would calmly fall, that they may labor to seek pleasure and sorrow,
some great. For, as we come to the smallest things, which of us ever undertakes
laborious physical exercise, except to obtain some advantage from it? But who
has any right to find fault, who wishes to enjoy a pleasure that has no annoying
consequences, or one who avoids a pain that, produces no resultant pleasure?

I have hopes of similarly revising my (Latin) Sans and Monospace fonts, perhaps
without breaking them down by font-style.

I also hope to use some (very short) monotonic Greek dummy text, taken from a
transliteration ofLorem Ipsum but with some added tonos and dialytika accents,
including on capital letters, with random letter substitutions to try to show
the whole lowercase alphabet. If I get time to do that, I think I might try to
separate regular modern text (upright) and slanted text.

For Han languages, it seems that, at least in XeLaTeX, only a few packages exist
to provide (non-garbled) filler text. I am inclined to create files showing some
codepoints which are known to differ between JP, KR, SC, TW and to include ALL
Noto Variants, plus WenQuanYiZenHei (default in fontconfig even for Serif) plus
fonts for a language and style. I was working towards doing that for SC Sans,
but while reviewing what words I will use for Korean (Sans/Serif) I found an old
LibreOffice bug report showing several other codepoints which differed in Serif
documentation. So that will all take a while longer.
