----------------------------------------
Summary: Cannot output unicode text to log file using
LOG4CXX_INFO/DEBUG/WARN/ERROR
Key: LOGCXX-453
URL: https://issues.apache.org/jira/browse/LOGCXX-453
Project: Log4cxx
Issue Type: Bug
Components: Appender, Documentation
Affects Versions: 0.10.0
Environment: Linux, Ubuntu, Trusty, Ubuntu 14.04
Reporter: Stephane Tremblay
I've got a program in C++ that uses a FileAppender to output log messages using
the macros LOG4CXX_DEBUG LOG4CXX_INFO LOG4CXX_WARN and LOG4CXX_ERROR.
We use unicode text strings in our project because our software will be used
around the world in different languages and locales. Every time we try to log a
message using one of the aforementioned macros and that message contains
accented characters such as é è ç, etc. the characters get replaces with
question marks.
For example, if I were to use LOG4CXX_INFO(logger, "François") the output in
the log file would be as follows:
Fran??ois
I've tried setting my LC_ALL locale in my environment variables, setting in in
the application with setlocale, I've tried calling the FileAppender's
setEncoding method, calling FileAppender's setOption method as well but to no
avail.
Also, setEncoding and getEncding are not documented. I assumed the proper
string to pass was "UTF-8", I also tried "en-US.UTF-8" and others, but that
didn't work either.
I might be mistaken, but I believe outputting unicode text to a log does not
work.
