I'm using Creole's
<<toc>> to list all pages on my wiki. When the macro detects a heading containing non-ASCII characters, like
= Sójka =
it stops processing the page, ignores the whole page in the TOC and spits out the error
Wiki macro error:
without giving any reason. Processing continues with the next page.
Removing the offensing character
= Sojka =
stops TOC macro whining and renders the page link correctly.
As I'm writing wiki pages in Polish, it is very common to have diacritics outside ASCII or Latin-1 in the headings.
