Is BIG5-2003 (CNS11643) included in iconv?

Issue

• Can not use iconv to convert characters from UTF-8 to BIG5-2003.

• Can not convert some character from UTF-8 to BIG5:

# cat from.txt 
厄夜迷踪
# iconv -f utf-8 -t big5 from.txt 
�̩]�giconv: illegal input sequence at position 9

• The word '踪' is not included in BIG5 character set, it is inclued by BIG5-2003.
