If a single Valentina project is developed across several machines and users with different locale settings, the point numbering starts anew, leading to a mess. For example, user №1 starts with A(English) , and creates points A1 to A27. The user №2 with, say, Russian locale steps in and tries to add a point. Automatic naming gives the user A(Russian)1, not A(English)28. The "A" letters are practically identical and it's difficult to detect where the problem is. Trying to manually change 1 to 28, 29 etc only makes things worse, and may require to make find/replace operations in the project xml source. It would be better to freeze prefix upon it's creation and save it to project.
