The po plugin is broken by po4a 0.58+

Hi Joey, maybe you have upgraded the machine running Branchable some time this summer or at late spring? It seems that Ikiwiki is now affected by an incompatibility with recent po4a versions.

• https://bugs.debian.org/700467
• https://ikiwiki.info/bugs/po:_buggy_UTF-8_support_with_po4a_0.58+/

Do you thing it would be possible to patch Ikiwiki on Branchable and in Debian ?

Thanks a lot for keeping Branchable available to its current users. It is very kind and I appreciate it a lot.

Charles
