Is locale ja not supported by libc in woody?

[hase@mech.usp.ac.jp (Hideaki Hase)]

Please, help me, any kind.

Setting ja (ja_JP.ujis, etc.) locale on my system, I'm reported:

    locale not supported by C library, ...

and got locale ignored.

My system is debian woody on i386 compatible.

Thanks.
