[Plugin: WordPress SEO by Yoast] Characters in og:description are replaced with "?" (&

Hey,

I started using romanian diacritics today, and saw that in the og:description tag certain characters (e.g. “ăĂțȚ”) are replaced with a quation mark.

_yoast_wpseo_opengraph-description is empty; the post excerpt display on the frontpage correctly.

The error originates in /inc/wpseo-functions.php, line 156:
'%%excerpt%%' => ( !empty( $r->post_excerpt ) ) ? strip_tags( $r->post_excerpt ) : utf8_encode( substr( strip_shortcodes( strip_tags( utf8_decode( $r->post_content ) ) ), 0, 155 ) ),

utf8_decode() fails to convert those characters to ISO-8859-1, so I removed that:
'%%excerpt%%' => ( !empty( $r->post_excerpt ) ) ? strip_tags( $r->post_excerpt ) : substr(strip_shortcodes(strip_tags($r->post_content)), 0, 155),

Cheers,
Alex
