Different text rendering in linux and windows while using text-wrap-width

[mohsentaleb]

I'm rendering a bunch of Arabic labels on the map, with "text-wrap-width:30" in tilemill and get different results in linux and windows (the latter one renders it with the correct direction).

P.S. Both tilemill apps connect to one Postgres data source (which ensures the data is absolutely the same)

Any ideas?

Hi @mohsentaleb - thanks for the report. I'm not sure why this would be happening. The Mapnik version used in each should be the same (assuming you are using TileMill packages, right?). Are you using TileMill 0.9.1?

It seems like it may be a subtle bug in the Mapnik code. For example, see also mapnik/mapnik#1429.

Yes, I'm using TileMill 0.9.1 on both Windows and Linux.
Is there any sort of information I can provide to help finding the bug?

This problem is almost certainly fixed by the RTL-aware rewrite of the line breaking code.
