"I used wsexport for generating epub file from cs.wikisource book. Then I copy it to my mobile and opened using Cool Reader app (but you can imagine any other e-book reader). Text of book and images were correct, but external link from infoboxes were with bad encoding." - JAn Dudík
Assuming this is about WS Export.
I cannot reproduce a problem.
- Go to https://wsexport-test.wmflabs.org/
- Enter cs and Blizzard ( https://cs.wikisource.org/wiki/Blizzard ).
- Click Export.
- Open resulting epub file in gnome-books 3.34.0 using libgepub 0.6.0 on my Linux machine.
Links in the infobox such as https://cs.wikisource.org/wiki/Autor:Josef_Ladislav_Turnovsk%C3%BD or https://cs.wikisource.org/wiki/Autor:V%C4%9Bnceslav_%C4%8Cern%C3%BD open without a problem here.
@JAnD: Can you please elaborate what "bad encoding" means exactly? What is the resulting URL which does not work? Which other e-book reader software has been tested? Thanks!
