## 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 <0.99.beta20, the "slang" driver does not support unicode. Note that libcaca <0.99.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.

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.
