(1) line break opportunities need to be determined by ICU and not use a hardcoded escape around ICU such as Font::isUnbreakableCharactersPair;

(2) the JLREQ document [1] is not a W3C recommendation; it is a collection of input requirements being considered for preparing normative recommendations, such as CSS3 Text, the current draft of which defines the recommended behavior in [2][3];

(3) the current Unicode Line Break class database marks U+3033 and U+3035 as ID (Ideograph) class, and not IN (Inseperable); in general, ICU and CSS3 Text make normative reference to this database for determining line break classes;

(4) there is already a pending patch in process [5] which will be adding line-break property support according to [3][6][7], so any change for JLREQ related line breaking should be handled as part of [5];
