I think we need to add a character set override mechanism to Horde.

I have a user that received a message in ks_c_5601-1987 (sent via  
Outlook in Korean).

This is a valid character set according to RFC 1345 and IANA  
(http://www.iana.org/assignments/character-sets)

libiconv claims to support this character set in their docs, but the  
software doesn't actually support it.

$ iconv -l | grep KS_C_5601-1987
ISO-IR-149 KOREAN KSC_5601 KS_C_5601-1987 KS_C_5601-1989 CSKSC56011987
$ iconv -f ks_c_5601-1987 -t utf-8 /tmp/foo.eml
iconv: /tmp/foo.eml:1:0: cannot convert

Other webmail systems have a mechanism to override the character set.

Horde should do something similar.
