Proposed Update UAX #14: Line Breaking Properties
http://www.unicode.org/reports/tr14/tr14-18.html

The UTC has modified the conformance clauses of UAX #14 and the text they
reference. These changes clarify precisely what is tailorable in conformant
implementations and what is not. The non-tailorable results are limited to
interactions among a small set of well-defined core characters, such as
CR, LF, NBSP, SP, and so on, where the semantics of the characters is bound
up in how they linebreak.

The rules of the algorithm have been reordered and restated to allow free
tailorability of most rules and the character properties they depend upon,
except for those rules involving the core set.

Reviewers should note that all the rules were renumbered, with a
correspondence table between rule numbers in the Modifications section.

The default assignments to linebreak classes for certain South East Asian
scripts have been adjusted to make it easier to interface with the kind of
external algorithm needed to handle these scripts correctly.  A few rules
have been added or modified to better reflect the behavior of currency
characters (and similar characters) in numbers, and the use of words like
"person(s)".

Other minor adjustments have been made to line break classes, rules and  
text.
