83 | * Send an ICBM (instant message). | |

86 | * Possible flags: | |
87 | * AIM_IMFLAGS_AWAY -- Marks the message as an autoresponse | |
88 | * AIM_IMFLAGS_ACK -- Requests that the server send an ack | |
89 | * when the message is received (of type 0x0004/0x000c) | |
7b91722d | 90 | * AIM_IMFLAGS_UNICODE--Instead of ASCII7, the passed message is |
91 | * made up of UNICODE duples. If you set | |
92 | * this, you'd better be damn sure you know | |
93 | * what you're doing. | |
94 | * AIM_IMFLAGS_ISO_8859_1 -- The message contains the ASCII8 subset | |
95 | * known as ISO-8859-1. | |
96 | * | |
97 | * Generally, you should use the lowest encoding possible to send | |
98 | * your message. If you only use basic punctuation and the generic | |
99 | * Latin alphabet, use ASCII7 (no flags). If you happen to use non-ASCII7 | |
100 | * characters, but they are all clearly defined in ISO-8859-1, then | |
101 | * use that. Keep in mind that not all characters in the PC ASCII8 | |
102 | * character set are defined in the ISO standard. For those cases (most | |
103 | * notably when the (r) symbol is used), you must use the full UNICODE | |
104 | * encoding for your message. In UNICODE mode, _all_ characters must | |
105 | * occupy 16bits, including ones that are not special. (Remember that | |
106 | * the first 128 UNICODE symbols are equivelent to ASCII7, however they | |
107 | * must be prefixed with a zero high order byte.) | |
108 | * | |
109 | * I strongly discourage the use of UNICODE mode, mainly because none | |
110 | * of the clients I use can parse those messages (and besides that, | |
111 | * wchars are difficult and non-portable to handle in most UNIX environments). | |
112 | * If you really need to include special characters, use the HTML UNICODE | |
113 | * entities. These are of the form ߪ where 2026 is the hex | |
114 | * representation of the UNICODE index (in this case, UNICODE | |
115 | * "Horizontal Ellipsis", or 133 in in ASCII8). | |
