I’ve seen that exception when I was running the Jenkins agent or the Jenkins controller in a locale that did not support the character I was trying to write. For example, if a file name or a directory name included a non-ASCII character and I was running in a locale that only supported ASCII (like the ‘C’ locale), then that exception would be reported.

Use the command `locale -a` to report the locale running on that agent. If it is not a UTF-8 capable locale, then reconfigure the agent startup environment to set the locale to a UTF-8 capable locale.
