Wrong text encoding for some stories in TecMundo feed

These are just random unreadable characters,this does not happens for all feeds I have,neither for all feeds of TecMundo,but some of them are not readable on the app,if I open their website I can read their post.

Is it their fault/bug or is it a newsblur app bug?

I see it too in the https://www.newsblur.com/site/461853/novidades-do-tecmundo feed. Looks like it’s their bug as they are reporting an incorrect encoding.

Thank you
