Exception Type: UnicodeEncodeError at /
Exception Value: 'ascii' codec can't encode characters in position 25-28: ordinal not in range(128)

Workaround is to use {% with %} tag:

{% with title='Тут не поддерживается юникод' %}
    {% opengraph_meta "url=/, title=title, type='website'" %}
{% endwith %}
