# Currently something strange is generated when using utf8, this needs a fix.
# I tried this solution, but it does not really work either (though the
# resulting output should be plain utf8 and the webbrowser is able to display
# things correctly, the wiki does not like it...
# Change text.encode to utf16 and do this to have the pasteable entry in the
# terminal (or redirect the output of the iconv line into a file and paste the
# content of it):
# ./data/tools/about_cfg_to_wiki > wiki_utf16
# iconv --from-code=utf16 --to-code=utf8 wiki_utf16
# rm wiki_utf16
