Custom characters on phi-panel

You can use all custom characters on phi-panels as long as you are not using them in a long message, which uses custom characters to display the scroll bar on the right.

You can do the following:

When you need to use custom characters, follow the sample code phi_panel_big_show between lines 167 and 189. The last command in that function prints “\eZ~” to the panel to reinitialize the panel’s internal custom characters. Otherwise you will see your custom characters in place of the scroll bar 🙂

You will need the custom character definitions in your code as well so:
The code may be a bit messed up by the blog posting restrictions but you can find original code in the beginning and between lines 167 and 189 of the sample code phi_panel_big_show.
