Caca limitations and bugs

The caca terminal has known bugs and limitations:

Unicode support depends on the driver and the terminal. The "x11" backend supports unicode since libcaca version 0.99.beta17. Due to a bug in libcaca 4#40.99.beta20, the "slang" driver does not support unicode. Note that libcaca 4#40.99.beta19 contains a bug which results in an endless loop if you supply illegal 8bit sequences.

Bright background colors may cause blinking.

Modifier keys are not supported for mousing, see term caca (p. [*]).

Rotated enhanced text, and transparency are not supported. The size option is not considered for on-screen display.

In order to correctly draw the key box, use

     set key width 1 height 1

Alignment of enhanced text is wrong if it contains utf8 characters. Resizing of Windows console window does not work correctly due to a bug in libcaca. Closing the terminal window by clicking the "X" on the title line will terminate wgnuplot. Press "q" to close the window.
