 When WP automatically generates a slug for a post with non-latin title AND
 a number has to be appended to the slug to avoid duplicate slugs, then the
 resulting slug may be badly truncated.

 To reproduce the problem:

 Create and publish a post with this title (without the quotes): "Αρνάκι
 άσπρο και παχύ της μάνας του καμάρι"
 Create and publish another one with this title (without the quotes):
 "Αρνάκι άσπρο και παχύ της μάνας του καμάρι, και άλλα τραγούδια"

 In both cases, let WP create the slug.

 You will see that the second slug is broken and the URL results in a 404
 error.

 It seems that, in this scenario, WP does not take into account the fact
 that the new slug may contain url-encoded characters from multibyte
 character sets, when truncating it.
