The JIS X 0208 needs an escape sequence. In Japan, the escape technique is ISO 2022. From basic ASCII, escape sequence “escape” $ B (in HEX, 1B 24 42) lets the parser know that following bytes should be handled 2-byte wise.

BIG-5 Code for Taiwanese Character Set (BIG-5)Code for Taiwanese Character Set (BIG-5)ADoes not need an escape sequence. BIG-5 does not need an escape sequence. ASCII is a 7 bit character set, which means that the top bit of the byte is “0”. The parser knows that when the top bit of the byte is “0”, the character set is ASCII. When it is “1”, the following bytes should be handled as 2 bytes (or more). No escape technique is needed. However, since some servers do not correctly interpret when they receive a top bit “1”, it is advised, in internet RFC, to not use these kind of non-safe non-escape extension.Does not need an escape sequence.

UNICODE UTF-8 UCS Transformation Format, 8-bit formUCS Transformation Format, 8-bit formAUTF-8 is a variable-length encoding, each code value is represented by 1,2 or 3 bytes, depending on the code value. 7 bit ASCII is a proper subset of UTF-8. Note that the code contains a space before UTF but not before and after the hyphen. Since UTF-8 represents the full UNICODE character set, the following restriction apply to its use: 1. UTF-8 must be the default encoding of the message, UTF-8 cannot be specified as an additional character set in MSH-18 2. There are no other character sets allowed in a message where UTF-8 is the default encoding in the message. In other words, UNICODE UTF-8 can only be specified as a single value in MSH-18 3. A message encoded in UTF-8 must not use a Byte Order Mark (BOM).UTF-8 is a variable-length encoding, each code value is represented by 1,2 or 3 bytes, depending on the code value. 7 bit ASCII is a proper subset of UTF-8.
