iconv_zh_HK - codeset conversion for HKSCS encodings


The table below provides basic information on available Hong Kong Supplementary Character Set code conversions.

The listed names in the table are canonical names. There are aliases, e.g., Big5-HKSCS, zh_HK.hkscs, and such for BIG5-HKSCS2008, that are also supported.

Character Set Code
Traditional Chinese multibyte codeset using US-ASCII as the single byte codeset and HKSCS-2004 character as two-byte codeset.
Traditional Chinese multibyte codeset using US-ASCII as the single byte codeset and HKSCS-2008 character as two-byte codeset.

Available iconv and cconv conversions in the current system can be obtained by running iconv -l as described in the iconv(1) manual page.

Additional information on the mappings between canonical names and supported aliases with optional variant levels, refer to alias(5) manual page and also /usr/lib/iconv/alias file.

For any characters that exist and legal in a fromcode that do not exist in a tocode of any of the above codesets, each of such characters will be converted into '?' (0x3f) as a non-identical code conversion. If the tocode is a Unicode encoding, U+FFFD (replacement character) will be used instead.
