Solved unacceptable character '?' (0x9E) special characters are not allowed

Hello,

Yesterday evening I came across the problem where none of my worldguard regions were working. After some testing it seems that the region file for my survival world contains one or more errors. I did not change anything to the file in weeks so I could not have caused it.
Error message:

Code:

I already searched the regions.yml file for the '?' symbol, but could not find it.

 

org.apache.commons.lang.UnhandledException: Plugin SimpleAFK v0.9.1 generated an exception while executing task 8

nothing to do with worldguard. just regenerate that plugin's config.

 

I already tried deleting the config. But the fact is that when I make Worldguard generate a new regions.yml file for my survival world, the issue is instantly solved. So the issue has to be in that file. Do you want me to upload the regions.yml file?

 

Open your regions.yml and search character ?
Someone added member with that name or something like that. Delete that character from member, and it will be ok.

I had problem ''unacceptable character '' (0x9E)", and deleted members with name '', and it worked

 

I see, someone tried to add a player to a region and somehow added some weird characters to the username. It looks like it works now. Thanks!
