I use halos on nearly every map I make. When exporting a map with haloed text, though, they always look something like this:
Here it is in Pro:
It seems that the halo itself is converting fine, but something's happening to the kerning.
In Pro, my character spacing is set to 0%, and the labeling option I am using doesn't even have an option to spread.
They should be 0 in Illustrator, then, too. When I hop over to Illustrator, though, I find that there are wildly different tracking values between characters.
If I select all and set them to 0, it looks fine. Why is the export messing with that? Luckily this map doesn't have that many labels and Illustrator has some good tools for selecting similar text, but it's just a little boggling that Pro is putting out a file that has altered tracking values.
Please improve the conversion of haloed text by keeping the tracking at the value set in Pro.
