Awaiting spec text
This issue is likely to apply to all cursive script text, but also to other scripts that have joins between letters.
When text stroke effects are applied to cursive text, they should not interrupt the cursive flow.
The GAP
Unfortunately, that's not the case for current implementations. Overlaps where the glyphs join produce double breaks in the cursive flow.
This example shows the typical result for Arabic.
The set of modern languages using cursive scripts includes those that use the following scripts: Arabic, Syriac, Mongolian, Mandaic, N'Ko, Adlam, Hanifi Rohingya. It also affects text in archaic scripts, including Phags Pa, Manichaean, Psalter Pahlavi, Sogdian, Old Uyghur, Chorasmian.
However, this also affects scripts such as Devanagari (Hindi, Marathi, etc), Gurmukhi (Punjabi), Bengali, Gondi, Modi, Newa, etc. This example is Hindi:
In Gecko, Blink, and Webkit the stroke around the text interrupts the cursive flow.
The property
text-strokeis not yet in CSS, but has been implemented in major browsers under the name-webkit-text-stroke.-webkit-text-strokeis currently specified in WhatWG's Compatibility spec.Priority:
Marking as advanced because this is a decorative feature.
