I have problems reading logs when it comes to filenames analyze if several languages are in use (my typical example - german umlauts ÖÄÜß and cyrillic letters ЯйЁ).
Log4Net has default encoding set to ACP = Default = ANSI http://logging.apache.org/log4net/release/sdk/log4net.Appender.FileAppender.Encoding.html
I suggest to add encoding definition to our log4net.config and set it to UTF-8:
<encoding value="utf-8" /> should be added to every appender definition in our log4net.configs (for both MP and TV parts) and also in TV part code generating default log4net.config file.
