--- Comment #2 from Ming Hua <ming.v.hua at qq.com> ---
Not exactly surprising, as the default line-breaking rule for (modern) Chinese
is "anywhere but some special place before/after punctuation marks", as we
don't use spaces to separate "words" at all.  And new exceptions to this rule
had to be introduced when Latin-and-Chinese mixed text layout was considered.

It's probably not hard to fix though, one just needs to treat non-breaking
spaces not as whitespace character when considering line-break positions.

It would be interesting to know if the same problem exists for Korean texts, as
they use spaces to separate words.  Japanese doesn't (just like Chinese) and
presumably is also affected.
