AppleLocale and Terminal bug?

[xvl]

In Mac OS X 10.6.7...

Japanese charaters works in Terminal.app while AppleLocale is set to en_US, en_GB or ja_JP.

But if I do:

defaults write -globalDomain AppleLocale sv_SE

and Log out and Log in. Then Terminal.app will display whitespaces instead of the charaters, both if I cat a file or open it in vim.

To reproduce, in Terminal.app:

$ cat
馬鹿たれ
馬鹿たれ
<Control+D>

Vim displays the correct UTF-8 hex values while the cursor is under a japanese character and pressing "g8", but Terminal.app will not display the character.

If I do not use the swedish locale, the week number will be incorrect, while date(1) displays:

$ date -v2011y -v4m -v23d '+%U %V %W'
16 16 16

All Cocoa apps that uses week number will display 17 /except/ for swedish when they display 16. (For 23rd of April).

In Terminal.app:

$ gcc  -xobjective-c -framework Foundation -
#import <Foundation/Foundation.h>

int
main(void)
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSDate *date = [[NSDate alloc] initWithString:@"2011-04-23 00:00:00 +0100"];
    NSDateFormatter *weekFormatter = [[NSDateFormatter alloc] init];
    [weekFormatter setDateFormat:@"w"];
	
    NSLog(@"%@", [weekFormatter stringFromDate:date]);
	
    [pool drain];
    return 0;
}
<Control+D>
$ defaults write -globalDomain AppleLocale en_GB
$ ./a.out
2011-04-24 16:51:52.956 a.out[49908:903] 17
$ defaults write -globalDomain AppleLocale sv_SE
$ ./a.out
2011-04-24 16:51:56.697 a.out[49928:903] 16
$ defaults write -globalDomain AppleLocale ja_JP
$ ./a.out
2011-04-24 16:52:02.432 a.out[49948:903] 17

I am not sure if there are any known workarounds or if I should file this as bugs to Apple?
