Thank you for your suggestions. It turns out that the issue is not
FreeBSD-specific: I was able to replicate it on Solaris. In the end, I
opted for implementing the transcoding in a custom taglib and upgrading
the app.

Thank you,


Sergei Komarov

You could try adding the following to the default class in
/etc/login.conf:
:charset=zh_CN.GB2312:\
:lang=zh_CN.GB2312:\
and then doing "cap_mkdb /etc/login.conf".

You could also have just mis-spelled the locale.
