Problems with nordic letters (?, ? and ?)

larsidar, can you share 1 example of each case (URLs)?

This article shows without these letters in Instant Articles (not live yet, still under review):

I have the same problem with special characters in brazilian portuguese language. Normal feed is ok, but the feed generated by the plugin is full of typos.

Url: bit.blog.br

This was fixed in this ticket https://github.com/Automattic/facebook-instant-articles-wp/issues/116

And it is available on version 2.9 of the WP plugin.
Can you please check if it works for you?

Thank you.

Doesn′t work now either. Still same problem.

What is the charset of your database? (utf-8, iso, …)?

What is the charset properties you have using: phpinfo()
