Description:
THREAD: http://www.w3.org/Mail/flatten/index?subject=I18N-ISSUE-334&list=www-style 8.2. Tracking: the ‘letter-spacing’ property http://www.w3.org/TR/css-text-3/#letter-spacing-property The section on "tracking" ('letter-spacing') may need to consider the effect on scripts such as Indic. The I18N WG asked for guidance from various Indic language contributors [1]. It was reported to use that 'letter-spacing' is not a native typographic style to these languages, however it is used in several languages, such as Hindi, for visual effect--if only rarely. The guidance we received, which is consistent with our understanding, is that letter-spacing should "break" the joining "bar" (shirorekha) in those scripts that use a "bar" and that the separation should be on syllable boundaries. These boundaries do not necessarily correspond to Unicode's default grapheme cluster boundaries, making proper description more complicated.
