Really great and quickly useful, at least for colors ! I first tried to put the symbol code instead of the symbol itself in the geojson but it didn't work.
Not all text editors show unicode characters. I'm using jedit and all the icons I tried are not displayed, even though they are well saved and displayed in collect. (For example it shows me the bird on Kiev but not the frog on Paris.
Is there any way to use the character code like we do for color? Wouldn't that make it easier to create geojson or csv?
I'm also thinking about this from the perspective of entities and the possibility of generating such properties with an expression.
For example, the material I inspected today was damaged, and I want it to be red the next time someone visits.
Regarding the shortcuts possibility, I have some difficulties to understand what happens and I need to spend more time to try it.
