after 2.2 MinimServer update following java error: Malformed input or input contains

[Exiled]

I have the same problem. After upgrading from 2.1.2 update 222 to 2.2 update 231, MinimServer fails to start and the log file shows the above error with reference to a file containing an accented character. I tried re-naming that file to eliminate the accent, and MinimServer now fails on the next file with accents in the file name.

In my case I have not changed locale or character set info. The MinimServer log contains the following both before and after the upgrade: "Platform default charset is US-ASCII".

MinimServer is running on Synology DSM 4.2. I've found a procedure to update system locale/char set on the NAS, but I'm not sure if it will have an impact on other applications so I'd prefer not to if there's an easier way around this problem.
