HI,
I am a chinese and I am using log4cxx as a logging facility in my
project(the locale in my linux server has been set to "zh_CN.GBK").
when I switch to the 0.10.0 release(I used version 0.97 beta before), I came
cross a problem: all the chinese logging message produced by my program
could not be displayed correctly.
Therefore, I decided to examine the source, and i found something which I
suspect was the cause of my problem, the suspected code is:
std::string Transcoder::encodeCharsetName(const LogString& val) {
char asciiTable[] = { ' ', '!', '"', '#', '$', '%', '&', '\'', '(',
')', '*', '+', ',', '-', '.', '/',
'0', '1', '2', '3', '4', '5', '6' , '7', '8',
'9', ':', ';', '<', '=', '>', '?',
'@', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
'I', 'J', 'K', 'L', 'M', 'N', 'O',
'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
'Y', 'Z', '[', '\\', ']', '^', '_',
'`', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h',
'i', 'j', 'k', 'l', 'm', 'n', 'o',
'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x',
'y', 'z', '{', '|', '}', '~', ' ' };
std::string out;
for(LogString::const_iterator iter = val.begin();
iter != val.end();
iter++) {
if (*iter >= 0x30 && *iter < 0x7F) {
out.append(1, asciiTable[*iter - 0x30]); // this is the
problematic line of code for me.
} else {
out.append(1, LOSSCHAR);
}
}
printf(out.c_str());
return out;
}
I replace the line "out.append(1, asciiTable[*iter - 0x30]);" to
"out.append(1, *iter);", then my problem was solved.(The input arguement of
this function is "GBK" in my system. Before I hacked the code, this function
resturn "12;"; After the hacking, this function return "GBK" which is my
desire result).
I don't understand why we need to change the name of the charset name(for
the fear of non-ascii charset names? even with that fear, I can't see the
need of changing from "GBK" to "12;")
