Could you also show examples how would other scripts look like with this change?

[sommerluk]

Note that the used line spacing is simply the same that we have also applied in the rest of openstreetmap-carto (−0.15 em for line wrap ≤ 3 em).

This is the last one of various PR that implemented the fine-tuned line spacing.

Screenshots look good to me, but I haven't tested the code.

[matthijsmelissen]

Thanks! By the way, it would also make sense to keep the wrap-width a constant em amount.

Closed without testing with Myanmar ?

[verdy-p]

And still no test for Arabic : (high Khufi font, suitable for real trafic signs where they are isolated and have cumfortable line-height) or UI font (better suited for multilingual text on a dense map) ?
I summary the tests above are only for alphabetic (Latin/Greek/Cyrillic) script, Indic script, CJK scripts, it will probably work for Hebrew and Tifinagh
But I still have doubts for Arabic, Myanmar, Khmer, Lao, and Tibetan, and possibly even with Thai.

[kocio-pl]

Could you provide test rendering for missing scripts?

[verdy-p]

All these scripts were in the initial #2358
When closing this bug with limited tests, someone marked #2358 as resolved even if you tested much less things here.
