In fact I am linking against libiconv from Blastwave.org at
/opt/csw/lib. However, the charset seems to be supported:

thor% /opt/csw/bin/iconv -l | grep UCS-4BE
UCS-4BE

The system trace looks like this:

16896:  sigprocmask(SIG_BLOCK, 0x080464E4, 0x080464C0)  = 0
16896:  sigprocmask(SIG_BLOCK, 0x080460B4, 0x08046090)  = 0
16896:  -> libiconv:libiconv_open(0xdf986e04, 0x80c1e90)

...and...

thor% mdb -p 16896
Loading modules: [ ]
 > 0xdf986e04/S
0xdf986e04:     646
 > 0x80c1e90/S
0x80c1e90:      UCS-4BE

Looks like there is no 646:

thor% /opt/csw/bin/iconv -l | grep 646
ANSI_X3.4-1968 ANSI_X3.4-1986 ASCII CP367 IBM367 ISO-IR-6 ISO646-US

CN GB_1988-80 ISO-IR-57 ISO646-CN CSISO57GB1988

Is this an error from zsh or is this a bug in libiconv?


Thanks!
