IOChannel.setEncoding

Sets the encoding for the input/output of the channel. The internal encoding is always UTF-8. The default encoding for the external file is UTF-8.

The encoding %NULL is safe to use with binary data.

The encoding can only be set if one of the following conditions is true:

- The channel was just created, and has not been written to or read from yet.

- The channel is write-only.

- The channel is a file, and the file pointer was just repositioned by a call to g_io_channel_seek_position(). (This flushes all the internal buffers.)

- The current encoding is %NULL or UTF-8.

- One of the (new API) read functions has just returned %G_IO_STATUS_EOF (or, in the case of g_io_channel_read_to_end(), %G_IO_STATUS_NORMAL).

- One of the functions g_io_channel_read_chars() or g_io_channel_read_unichar() has returned %G_IO_STATUS_AGAIN or %G_IO_STATUS_ERROR. This may be useful in the case of %G_CONVERT_ERROR_ILLEGAL_SEQUENCE. Returning one of these statuses from g_io_channel_read_line(), g_io_channel_read_line_string(), or g_io_channel_read_to_end() does not guarantee that the encoding can be changed.

Channels which do not meet one of the above conditions cannot call g_io_channel_seek_position() with an offset of %G_SEEK_CUR, and, if they are "seekable", cannot call g_io_channel_write_chars() after calling one of the API "read" functions.
