Hello.
There are codepage corruption while agent (for windows) collects data.
Data collected directly by agent is in correct codepage (for example - software inventory). But data collected by plugins is corrupted.
I have try to debug the issue by calling agent with /local /xml options. When the data collected I can see files named like plugin_name.vbs.xml This file created with codepage 866 (default for russian) and data is correct. But when output combined into result HOSTNAME.xml file the data corrupted. Codepage for result file detected as UTF8 but plugin output putted into file as-is without codepage conversion. AT this point all russian character displayed as "?".
