I've been experimenting with replacing my app's logging with Apple System Logger. When it comes to multi-byte characters, every thing looks OK in Console.app. However, Xcode's console shows things incorrectly. It probably won't come up often, but I'm wondering if it's fixable.

For example, this bit of code:
        NSLog(@"あ");

        asl_log(client, NULL, ASL_LEVEL_ERR, "あ");
        asl_close(client);

Results in this output in Xcode:
        2008-10-28 13:49:19.767 ASL[3484:10b] あ
        Tue Oct 28 13:49:19 iMac.local ASL[3484] <Error>: \M-c\M^A\M^B

The call to NSLog displays correctly, but asl_log doesn't.

aslclient client = asl_open(NULL, NULL, ASL_OPT_STDERR); // add STDERR's fd to the connection's set of fds so things show up in Xcode's console

to the database correctly.


in the source code) so you could, in theory, handle it if you had to.


be doing something like this:

char *hiragana_a = { 0xE3, 0x81, 0x82, 0x00 };

asl_log(client, NULL, ASL_LEVEL_ERR, a);

This is a known issue... you can see where the mangling happens in the source code online when writing to stderr... the characters are properly encoded when sent to syslog and will show up correctly in asl queries and the console application, as you saw. I output japanese to logs a lot and have never really had a problem, except that during debugging I have to use console in those cases and not rely on general output. There are a number of bug reports on the issue, but I doubt it's a very high priority since it write the log If you absolutely need this functionality, it's actually encoding it in some visual encoding form (you can see more about the form Also, you should not be using non-ascii characters in string literals :) hopefully you're just doing this to demonstrate the issue. You should NSLog(@"%@", [NSString stringWithCString:a encoding:NSUTF8StringEncoding]);
