------------------------------------------
{CODE}
The encoding is ISO-8859-8
[...]
log4cxx_logchar_is_utf8=1
{CODE}
So what exactly is your internal string encoding you forward to log4cxx? I've
always thought those LOGCHAR_IS defines tell log4cxx which encoding to expect,
so e.g. I'm just using WCHAR defines and wchar_t based Unicode strings. But
that might be wrong, I guess it should work to tell about UTF-8 and provide
locale dependent encoded strings, because at least in case of the console
appender log4cxx tries to encode stuff and that encoding takes into account fi
the current locale is UTF-8 or not. So check the following snippets and which
chars are available at which place and the define LOG4CXX_CHARSET_UTF8, which
is always 0 in my case for example. You need to debug which locale Transcoder
tries to use for encoding, if any.
systemoutwriter.cpp:
{CODE}
void SystemOutWriter::write(const LogString& str) {
#if LOG4CXX_WCHAR_T_API
[...]
#endif
LOG4CXX_ENCODE_CHAR(msg, str);
fputs(msg.c_str(), stdout);
}
{CODE}
transcoder.h:
{CODE}
#define LOG4CXX_ENCODE_CHAR(var, src) \
std::string var; \
log4cxx::helpers::Transcoder::encode(src, var)
{CODE}
transcoder.cpp:
{CODE}
void Transcoder::encode(const LogString& src, std::string& dst) {
#if LOG4CXX_CHARSET_UTF8 && LOG4CXX_LOGCHAR_IS_UTF8
dst.append(src);
#else
static CharsetEncoderPtr encoder(CharsetEncoder::getDefaultEncoder());
dst.reserve(dst.size() + src.size());
LogString::const_iterator iter = src.begin();
#if !LOG4CXX_CHARSET_EBCDIC
for(;
iter != src.end() && ((unsigned int) *iter) < 0x80;
iter++) {
dst.append(1, *iter);
}
#endif
if (iter != src.end()) {
char buf[BUFSIZE];
ByteBuffer out(buf, BUFSIZE);
while(iter != src.end()) {
log4cxx_status_t stat = encoder->encode(src, iter, out);
out.flip();
dst.append(out.data(), out.limit());
out.clear();
if (CharsetEncoder::isError(stat)) {
dst.append(1, LOSSCHAR);
iter++;
}
}
encoder->encode(src, iter, out);
}
#endif
}
{CODE}
charsetencoder.cpp:
{CODE}
CharsetEncoder* CharsetEncoder::createDefaultEncoder() {
#if LOG4CXX_CHARSET_UTF8
return new UTF8CharsetEncoder();
#elif LOG4CXX_CHARSET_ISO88591
return new ISOLatinCharsetEncoder();
#elif LOG4CXX_CHARSET_USASCII
return new USASCIICharsetEncoder();
#elif LOG4CXX_LOGCHAR_IS_WCHAR && LOG4CXX_HAS_WCSTOMBS
return new WcstombsCharsetEncoder();
#else
return new LocaleCharsetEncoder();
#endif

> Not able to see hebrew values when logging in log4cxx

> Key: LOGCXX-483
> URL: https://issues.apache.org/jira/browse/LOGCXX-483
> Project: Log4cxx
> Issue Type: Bug
> Environment: Linux Debian 8 32bit
> Reporter: Giora Guttsait
>
> When logging messages with a console appender (whose output is directed to a
> file), hebrew text is shown as weird symbols.
> It really affects out ability to debug and analyze the program output at
> specific points, so a quick fix(if possible) would be great
