difference in width depending on OS
trafficstars
When tracking down a difference between 2 systems regarding width of a flextable table, I found that the difference could be traced down to m_str_extents_
I get the following when running on a Red Hat

Any ideas on how I can fix this such that these widths will be the same?
I see there is some UTF-8 handing at https://github.com/davidgohel/gdtools/blob/master/src/font_metrics.cpp#L63-L68 Not sure this is related
The metric is still calculated with cairo, you can check this is the same version with gdtools::version_cairo().
Also, and prior to this, make sure you have and use the same font family (Verdana) on both systems. If not sure, try with gdtools::register_gfont("Open Sans").
