The settings for Charset are:

Value	Constant	Description
1	mailCharsetUSASCII	The default character set using US-ASCII which defines 7-bit printable characters with values ranging from 20h to 7Eh.
2	mailCharsetISO8859_1	An 8-bit character set for most western European languages such as English, French, Spanish and German. This character set is also commonly referred to as Latin1.
3	mailCharsetISO8859_2	An 8-bit character set for most central and eastern European languages such as Czech, Hungarian, Polish and Romanian. This character set is also commonly referred to as Latin2.
4	mailCharsetISO8859_5	An 8-bit character set for Cyrillic languages such as Russian, Bulgarian and Serbian.
5	mailCharsetISO8859_6	An 8-bit character set for Arabic languages. Note that the application is responsible for displaying text that uses this character set. In particular, any display engine needs to be able to handle the reverse writing direction and analyze the context of the message to correctly combine the glyphs.
6	mailCharsetISO8859_7	An 8-bit character set for the Greek language.
7	mailCharsetISO8859_8	An 8-bit character set for the Hebrew language. Note that similar to Arabic, Hebrew uses a reverse writing direction. An application which displays this character should be capable of processing bi-directional text where a single message may include both right-to-left and left-to-right languages, such as Hebrew and English.
8	mailCharsetISO8859_9	An 8-bit character set for the Turkish language. This character set is also commonly referred to as Latin5.

The settings for Enctype are:

Value	Constant	Description
1	mailEncoding7Bit	Each character is encoded in one or more bytes, with each byte being 8 bits long, with the first bit cleared. This encoding is most commonly used with plain text using the US-ASCII character set, where each character is represented by a single byte in the range of 20h to 7Eh. Most e-mail messages are composed using 7-bit ASCII.
2	mailEncoding8Bit	Each character is encoded in one or more bytes, with each byte being 8 bits long and all bits are used. 8-bit encoding may be used with multi-byte character sets, although this encoding type is uncommon in e-mail messages. It is recommended that quoted-printable encoding be used for 8-bit character sets.
3	mailEncodingBinary	Binary encoding is essentially the absence of any encoding performed on the message data, and there is no presumption that the data contains textual information. No character set localization or conversion is performed on binary encoded data. This encoding type is not recommended. Instead, binary data should be encoded using the standard base64 algorithm.
4	mailEncodingQuoted	Quoted-printable encoding is designed for textual messages where most of the characters are represented by the ASCII character set and is generally human-readable. Non-printable characters or 8-bit characters with the high bit set are encoded as hexadecimal values and represented as 7-bit text. Quoted-printable encoding is typically used for messages which use character sets such as ISO-8859-1, as well as those which use HTML.
5	mailEncodingBase64	Base64 encoding is designed to represent binary data in a form that is not human readable but which can be safely exchanged with servers that only accept 7-bit data. Base64 encoding is typically used with file attachments.
6	mailEncodingUucode	Uuencoding and uudecoding is a legacy encoding format that was used before the MIME standard was established. This encoding method has largely been replaced by base64 encoding, although it is still commonly used for binary newsgroup postings on USENET. Although this encoding format is supported, it is not officially part of the MIME standard and its use in e-mail messages is discouraged.
