I set the STYLE to ARIAL
In MTEXT, I typed your code instead of hunting for it manually, like this
Either your "arial" font is not the one I used in the sample, or something else is going on. If you get a chance, share one of your files with the wrong mtext symbol (and point to it).
Entering the code works perfectly. Thank you very mcuh!!!
I'm happy to upload a file if you're still interested, but this is a easily workable solution for me, probably easier than finding it in the symbol library. You've made my day, hope you have a good one too
Thanks everyone for your help.
