If the user on Windows has their default user name set as for example Norris Huć (or any other non-english letter), when running the PIVX Core wallet for the first time, PIVX Core wallet will offer the following default data directory:
C:\Users\Norris Huc\AppData\Roaming\PIVX

Issue is that PIVX Core wallet will recognize the default folder incorrectly by dropping the non-english letter and replacing it with english letter (ć -> c). So, of course, there will be an issue and impossible to start the wallet by going further without manually changing the c to ć, because there is no folder nor user in Users called Norris Huc.

OS: Windows 10
