1774851 - CSS hyphenate-character property does not handle multi-character strings correctly in RTL context

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect, P3)

Description

[Jonathan Kew [:jfkthame]]

When hyphenate-character is given a multi-char string, it always renders the string as LTR. Noticed when looking at bug 1774822 and trying to use

hyphenate-character: '\2005\0640';

for a kashida character preceded by a space. In Uighur (RTL) content, this ought to render a kashida with space to the right of it, but in fact the space appears to the left, and the kashida butts up against the preceding text (on its right).
