Comment:

 [attachment:31328.patch] fixes `utf8_uri_encode()` to support 4-byte
 sequences.

 This resolves the issue on display, but still breaks on editing, see
 [attachment:31328.edit-slug.png].

 [attachment:31328.2.patch] (based on a
 [http://stackoverflow.com/questions/12807176/php-writing-a-simple-
 removeemoji-function Stack Overflow thread]) also strips Emoji in
 `sanitize_title_with_dashes()`, similarly to [18705] and [20686].
