It seems that the fonts 'Sazanami Gothic','さざなみゴシック' and Sazanami Mincho','さざなみ明朝' have the wrong graph at U+7e6b (繫) which should have thread 糸 at the bottom, not hand 手.
Screenshot of a font test of 繫:
A more recent version of the font may have been fixed, I'll try it later. Accessing the (possible) webpage of the developer failed:

Update: still wrong in Slackware 14.2.
