Hi Deri,

I've noticed another similar issue, this time with Chinese.

I see chinese letters in the bookmarks, but they don't appear in the
PDF body.  If I read the manual page in the terminal, I do see them.
When generating the PDF, I get a bunch of warnings about special
characters not defined.


See the page head(1):

	$ MANWIDTH=64 man ./man/zh_CN/man1/chage.1 | head -n4
	CHAGE(1)                 User Commands                CHAGE(1)

	名称
	     chage - 更改用户密码过期信息

And here's how I generated the pages:

[ And a bunch of similar warnings... ]
