InitializeMime is a Procedure used to detect the transfer encoding, content encoding, and character used on the local computer system. InitializeMime uses the default values when a MBCS character set is not used on the local system, that includes the following:
- TransferHeader - bit8 (8-bit)
- HeaderEncoding - "B" (Base64)
- MimeCharSet - "ISO-8859-1" (ISO-Latin)
When the local system uses a MBCS character set, the MIME character set and content encoding are updated, and the Header encosing is set to Quoted-Printable ("Q").
