For background, Annex 14 is very permissive, implicitly allowing line breaks wherever they are not explicitly disallowed and does not, for example, disallow breaks following closing punctuation, allowing for example, this break:

"e. g., a thing"

That is, Annex 14 allows this break, even though it would be wrong in any Western language I'm familiar with.

However, the statement is incorrect. UAX#14 allows breaks after closing punctuation, but not if it precedes alphabetic characters.

That's good to know.

However, I will comment that in my reasonably close (but somewhat late-night) reading of Annex 14, I did not see this--the way the rules are defined makes it pretty difficult to decode the rules without a really close reading--and I'm a person whose spent most of the last 10 years writing and decoding complex standards.

I know that standards writers are always strapped for resources and that these sorts of annexes always get a lower priority, but it would be helpful if this annex could be made a little clearer, I think. At a minimum, a bit more discussion of the implications of the rules might be helpful.
