Checkmk Werk 10563: Linux agent: Fix possible encoding issues of Python plugins

ID: 10563 Title: Linux agent: Fix possible encoding issues of Python plugins Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 In previous versions the agent was not setting the encoding information in the environment, making Python plugins fail with <tt>UnicodeEncodeError</tt> exceptions when executed through the agent. Confusingly, the same command has often worked in interactive debugging, since the interactive shells of the users have set the encoding correctly The Linux agent is now setting <tt>LC_ALL</tt> to C.utf8 (in case the locale is available on the monitored system) instead of only <tt>LC_ALL=C</tt>. When the encoding is not set in the environment, Python will encode all the output written to stdout/stderr with <tt>ANSI_X3.4-1968</tt>. This will fail when there are non-ASCII characters in the output. Once the encoding is set, Python can detect it and encode all output using UTF-8.
