In #337 we decided to key line-break transformation behavior by Unicode Block. Most of the blocks are pretty straightforward: Han, Kana, Yi, and CJK punctuation blokcs discard, and everything else converts to a space. But there are a few interesting cases...
One interesting case is the enclosed ideographic blocks:

The numerics in the Letters and months block seem likely to be used outside of CJK context, also there are quite a few Hangul, and I wouldn't be surprised if at least some of the other characters are also used in Korean sometimes.
Note, however, that we only discard if both sides (before and after) the line break are part of the space-discarding character set.
