Hello XeTeXers,
Sorry for a not-entirely-XeTeX-related request but I think there may be some
merit in it for XeTeX in the future.
I have recently been toying around implementing my own layout engine, and have
started to check that it works nicely with non-Roman scripts. This has already
thrown up a few bugs in pango (which I'm using to do the shaping), and that's
just with scripts that I can read. I am sure there are other problems in
scripts I can't read.
So I thought it would be a useful thing for people like
pango/xetex/graphite/harfbuzz/other layout and rendering tool developers to
have a visual test suite, a collection of short strings which stress-test
their engines in interesting ways: placement of composing characters,
mandatory ligatures, mixed LTR/RTL, that sort of thing.
I have started putting a collection together but my own knowledge and
experience is pretty limited. If you can contribute some short Unicode strings
from a language you know which show an interesting rendering feature, I hope
this will be something that can be beneficial to the text layout community as
a whole.
The test suite at the moment is at
http://simoncozens.github.io/visual-testsuite/testsuite.html
and you can contribute via github at
http://github.com/simoncozens/visual-testsuite
(or just send me an email)
Thanks!
Simon
