PUBLIC int16 INTL_DefaultMailCharSetID (int16 csid)

Return the charset used in internet message from a specified charset

Documentation

Return the charset used in internet message from a specified charset. In the current implementation of Communicator, we assume there is a many to one relationship between a encoding and a encoding used on internet mail message. This routines is used to get the outgoing encoding for a specified encoding. The caller than can convert the text of the specified encoding to the return encoding and before send out the internet message. Usually the relationship is the same as the newsgroup posting and this one. However, for some region/country like Korean, it is not the same. In such region/country, they use different encodings in internet mail message and newsgroup posting. In that case INTL_DefaultNewsCharSetID should be used instead. Issues: The current model assume the text of a particular encoding is always sending out as one encoding. Such assumption break when people want send out message in different Cyrillic, Chinese, or Unicode encoding. Therefore, we may change this architecture in the near future. The mapping are:
  • CS_ASCII: CS_ASCII
  • CS_LATIN1: CS_LATIN1
  • CS_JIS: CS_JIS
  • CS_SJIS: CS_JIS
  • CS_EUCJP: CS_JIS
  • CS_JIS_AUTO: CS_JIS
  • CS_SJIS_AUTO: CS_JIS
  • CS_EUCJP_AUTO: CS_JIS
  • CS_KSC_8BIT: CS_2022_KR [Note 1]
  • CS_KSC_8BIT_AUTO: CS_2022_KR [Note 1]
  • CS_GB_8BIT: CS_GB_8BIT
  • CS_BIG5: CS_BIG5
  • CS_CNS_8BIT: CS_BIG5
  • CS_MAC_ROMAN: CS_LATIN1
  • CS_LATIN2: CS_LATIN2
  • CS_MAC_CE,: CS_LATIN2
  • CS_CP_1250: CS_LATIN2
  • CS_8859_5: CS_KOI8_R [Note 2]
  • CS_KOI8_R: CS_KOI8_R [Note 2]
  • CS_MAC_CYRILLIC: CS_KOI8_R [Note 2]
  • CS_CP_1251: CS_KOI8_R [Note 2]
  • CS_8859_7: CS_8859_7
  • CS_CP_1253: CS_8859_7
  • CS_MAC_GREEK: CS_8859_7
  • CS_8859_9: CS_8859_9
  • CS_MAC_TURKISH: CS_8859_9
  • CS_UTF8: CS_UTF7
  • CS_UTF7: CS_UTF7
  • CS_UCS2: CS_UTF7
  • CS_UCS2_SWAP: CS_UTF7
