Using tm, you can <ul> <li> playback or view the MIME messages using tm-view <li> compose MIME message using tm-edit <li> use the enhanced MIME features with mh-e, GNUS, Gnus, RMAIL and VM </ul> <noindent> and more. <p> Please read following about each topics: <ul> <li><a file="gnus-mime-en">tm-MUA for Gnus</a> <li><a file="tm-gnus-en">tm-MUA for GNUS</a> <li><a file="tm-mh-e-en">tm-MUA for mh-e</a> <li><a file="tm-view-en">mime/viewer-mode</a> <li><a file="tm-edit-en">mime/editor-mode</a> </ul> <h2> Glossary <node> Glossary <h3> 7bit <node> 7bit <p> <concept>7bit</concept> means any integer between 0 .. 127. <p> Any data represented by 7bit integers is called <concept>7bit data</concept>. <p> Textual string consisted of Control characters between 0 .. 31 and 127, and space represented by 32, and graphic characters between 33 .. 236 are called <concept>7bit (textual) string</concept>. <p> Traditional Internet <a node="MTA">MTA</a> can translate 7bit data, so it is no need to translate by <a node="Quoted-Printable">Quoted-Printable</a> or <a node="Base64">Base64</a> for 7bit data. <p> However if there are too long lines, it can not translate by 7bit MTA even if it is 7bit data. <dref>RFC 821</dref> and <dref>RFC 2045</dref> require lines in 7bit data must be less than 998 bytes. So if a ``7bit data'' has a line more than 999 bytes, it is regarded as <dref>binary</dref>. For example, Postscript file should be encoded by Quoted-Printable. <h3> 8bit <node> 8bit <p> <concept>8bit</concept> means any integer between 0 .. 255. <p> Any data represented by 8bit integers is called <concept>8bit data</concept>. <p> Textual string consisted of Control characters between 0 .. 31, 127, and 128 .. 159, and space represented by 32, and graphic characters between 33 .. 236 and 160 .. 255 are called <concept>8bit (textual) string</concept>. <p> For example, <dref>iso-8859-1</dref> or <dref>euc-kr</dref> are coded-character-set represented by 8bit textual string. <p> Traditional Internet <a node="MTA">MTA</a> can translate only <dref>7bit</dref> data, so if a 8bit data will be translated such MTA, it must be encoded by <dref>Quoted-Printable</dref> or <dref>Base64</dref>. <p> However 8bit MTA are increasing today. <p> However if there are too long lines, it can not translate by 8bit MTA even if it is 8bit data. <dref>RFC 2045</dref> require lines in 8bit data must be less than 998 bytes. So if a ``8bit data'' has a line more than 999 bytes, it is regarded as <dref>binary</dref>, so it must be encoded by Base64 or Quoted-Printable. <h3> 94-character set <node> 94-character set <p> <concept>94-character set</concept> is a kind of 1 byte <dref>graphic character set</dref>, each characters are in positions 02/01 (33) to 07/14 (126) or 10/01 (161) to 15/14 (254).
