I don't know what it looks like without word wrap but I think multiple lines is better if the text is really too long (e.g. "?????????"). I did have a suggestion on how the word wrap should be done for cjk (see the last few lines in the description of this bug[2]) i.e. it may be better to keep each lines roughly the same length.

It might be a better idea to increase the threshold (maximum length) if there is not a single space in the text and use some better method to do word wrapping in such case. This may work for any language that allow word wrapping (I personally don't know any language that does not, correct me if I am wrong.....) (including English (for extremely long words) if you add "-" correctly).

Why? The minimum width is hardly a limit for a long (english) string.

Have a look at https://git.reviewboard.kde.org/r/108328/s/1015/
The info icon has quite some glyphs even chinese, ie. CJK does not gurantee short strings - correct?
Not using a fixed size grid (but icons of variable width) can be considered a usability bug, for sure it looks dull.

As consequence you can have one item with a long line determine the width of all icons and by this cause a pretty spare view. That's hardly a solution either.

The "problem" (assumed from western esthetics) with the chinese glyphs in that screenshot is the wraps for one of them (or maybe two) what could be avoided by relaxed maximum bounds.

You'd have to (in the reimplemented ::paint() function of QItemDelegate) match the width of the remaining words against the textrect width, if it's "not much more" (tm) you'd paint it ignoring clips, otherwise break at the flooring word, move to the next line and go on with the rest of the string.
