.\" What the command does.
56
is a psuedo tty program that will translate Chinese encodings automatically
57
on a console. Supported encodings are BIG5/GB2312/HZ/UTF-7/UTF-8/UCS.
62
except that yyt will make things automatic all the way.
64
Yi Yan Tang use Saka's libhz to detect and convert Chinese encodings. libhz
65
is include in autoconvert and can be found at http://www.debian.org/~ygh/.
69
supports following Chinese encodings for both input and output:
71
.B "GB2312, BIG5, HZ, UTF-7, UTF-8, UCS"
74
supports following command line options:
75
.IP "\-f \fIencoding\fP or \-\-from=\fIencoding\fP"
76
This option sets the encoding of the incoming text. The valid values of
77
encoding are specified above.
78
.IP "\-t \fIencoding\fP or \-\-to=\fIencoding\fP"
79
This option sets the encoding of the local terminal. The valid values of
80
encoding are specified above.
82
This option prints out the usage of yyt.
83
.IP "\-V or \-\-version"
84
Gives the current version of ytt.
87
If the \-\-from encoding is not set, yyt will guess the encoding of the
88
incoming text. You can safely type the command:
92
to start the program. Then you can use the command-mode described below
93
to control how yyt acts.
95
There are some on the fly commands which can be used to control the
98
once it is started. User can use these commands to switch encoding,
99
disable auto-encoding-detection or turn off encoding conversion all
102
To active the yyt command mode, press the combination key
108
(for switch-on-YYT-command-mode). Then follow a single key command. Once
109
the command is entered, the command mode is switched off.
111
The possible commands in the command mode are:
113
For switch incoming encoding to
117
For switch incoming encoding to
121
For switch incoming encoding to
125
For switch incoming encoding to
129
For switch incoming encoding to
133
For switch incoming encoding to
137
For reset encoding state to the initial mode.
139
For turn off all the encoding conversions.
141
For set the incoming encoding to auto-detect mode.
145
keycode to the terminal so that ctrl-y can still be typed in.
148
If the incoming encoding is explicitly set either through command line
149
options or on line command, the user input is also converted from the
150
terminal encoding to the incoming encoding.
153
If set, the incoming encoding will be set to the encoding of LC_CTYPE.
154
LC_CTYPE will be Overriden by the
159
If set and there are no command line option given for [command...], the
160
SHELL will be executed on the start of the program.
162
Please see BUGS section.
164
yyt tries to segment a stream of text into Hanzi parts and English parts. That
165
way, we can have a better guessing on the Chinese encodings for every small
166
part of Chinese. However, Hanzi segmentation does not always work correctly,
167
especially when using curses/slang based programs. Redraw screen (normally
168
ctrl-l) sometime correct it. This problem is expected. Suggestions on better
169
segmentation algrithm are always welcomed.
171
Turn off auto-detection by specify a fromcode by (ctr-y
173
) will give better conversion result.
