156 <big><b>Unicode and UTF-8 Strings in Client Library</b></big>
159 This document describes how the client library handles UTF-8 encoded
160 strings. By default all strings in the SILC protocol are UTF-8 encoded.
161 All strings that are sent to server and strings that are received from the
162 server are always UTF-8 encoded. It is application's responsibility to
163 render the strings as well as possible on the user interface.
166 Exception to these strings are messages sent and received in
167 <a href="silcmessage-SilcMessagePayload.html">Message Payload</a>, which
168 can include practically any kind of strings with any kind of character
169 encodings, and binary data also. If UTF-8 encoded message is sent
170 or received it is indicated with the SILC_MESSAGE_FLAG_UTF8, and
171 application can render the messages accordingly.
174 Other strings are always UTF-8 encoded and application needs to decode
175 the strings to other character encoding if application does not support
176 UTF-8 rendering on user interface. Also strings application sends to
177 library, such as, nicknames, channel names, server names, host names,
178 topic srings, any command argument, etc. must always be UTF-8 encoded
179 before they are sent to the library. The <a href="silcutf8.html">UTF-8
180 routines</a> help the application developer to encode and decode
184 The client library does not ever encode or decode strings to or from the
185 current locale. The library always expects that all strings it receives
186 from application are already UTF-8 encoded. The library may validate
187 certain UTF-8 strings and return error if needed. Server may also
188 send errors in command reply if strings are not encoded properly.
191 Nicknames and channel names in SILC are also UTF-8 encoded and can
192 include practically any kind of letters, numbers and punctuation
193 marks. Control characters and other special characters are not allowed
194 in nickname strings, and application never receives such nicknames
195 or channel names from the library.
