If you want to use downloaded missions from Steam Workshop on your dedicated server, all "Spacebars" (or other special symbols) in missionname shown in a unfavorable cryptic "%20" format. This makes the missionlist very confusing!
Here an example:
Rename the PBO files directly causes strange server problems (crashes or heavy slow down...). UnPBO via ArmaTools doesnt works as well. There some other tools to UnPBO but this cant be the answer and also takes lot of time.
Feature-Request: The %20 etc. should be detected by Arma and corrected back into the source filename like they are named on Steam!
